thermastat maybe sticking or to high of a temp thermastat. change it to recommended type from auto parts store and you will have heat.

check the air pressure in all of the tires including the spare it has a monitor on it on some of these newer things.....hope it helps

TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle.

The TPMS is designed to alert the driver, if a low tire pressure condition exists. This system also allows the driver to check tire pressure levels using the Driver Information Center (DIC).

When a low tire pressure condition is detected, the TPMS displays the "CHECK TIRE PRESSURE" warning message on the DIC, and at the same time illuminates the low tire pressure warning symbol.

You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the "CHECK TIRE PRESSURE" message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

The "CHECK TIRE PRESSURE" warning message and low tire pressure light (telltale) will appear at each ignition cycle until the tires are inflated to the correct inflation pressure.

The Tire and Loading Information label (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold.

Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance.

NOTICE: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

RESETTING THE TPMS IDENTIFICATION CODES
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched to a sensor, by increasing or decreasing the tire's air pressure. The sensors are matched to the tire/wheel positions in the following order: LF TIRE (left front tire on the driver's side of the vehicle), RF TIRE (right front tire on the passengers side of the vehicle), RR TIRE (right rear tire on the passengers side of the vehicle), and LR TIRE (left rear tire on the driver's side of the vehicle).

You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.

The TPMS sensor matching process is outlined below:

1. Set the parking brake.
2. Turn the ignition switch to "RUN" with the engine off.
3. Turn the headlamp switch from "OFF" to the parking lamps setting four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The "SERVICE TIRE MONITOR" message will be displayed on the Driver Information Center (DIC).
4. Start with the driver's side front tire.
5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with Step 1. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage or a key.
6. Proceed to the passenger's side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger's side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver's side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If it is, turn the ignition switch to LOCK to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
11. Put the valve caps back on the valve stems. The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the "CHECK TIRE PRESSURE" message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The "SERVICE TIRE MONITOR" message is displayed when the TPMS is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed.

Hello: Check the coolant level if the surge tank is not at proper level (threre is a full line on the container) If the container is low then you may have a leak in your cooling system.

It could be the cluster but I would look at the speed sensor first. It is located on the transmission. You should get a Haynes manual on your vehicle from the local auto parts store before going into the job.

When you replaced the alternator , did you inspect the connections?
I have seen quite a few GM cars and trucks with bad connections at the altenator cause this issue

The fuel filter is located on the left frame rail midpoint near the transmission crossover,relieveing fuel pressure on these can be a bit tough,what i do is put a drain bucket under the filter and crack open the fitting enough so the fuel will begin to come out,just let it drain into the bucket until pressure is gone,remove the filter. The fuel filter is located underneath the vehicle on the driver side, almost under the driver seat. You can't miss it, just follow the gas lines coming from the fuel tank.
The sending unit is mostly plastic bt the pump itself is metal as well as the rods and springs that connect the pump/filter assembly to the top part that sits flush with the top of the tank and where the hose connections are (it's spring loaded to hold the pump against the bottom of the tank). The detailed procedure to remove filter is as follows:-- WARNING: Relieve the fuel system pressure before servicing fuel system components In order to reduce the risk of fire and personal Injury. After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the chance of personal Injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may leak out. Place the towel In an approved container when the disconnection Is complete .
Disconnect the negative battery cable in order to avoid possible fuel discharge if an accidental attempt is made to start the engine.
Loosen the fuel filler cap in order to relieve the tank vapor pressure.
Connect the gauge J 34730-1A or the equivalent to the fuel pressure connection.
Wrap a shop towel around the fitting while connecting the gauge in order to avoid spillage.
Install the bleed hose into an approved container and open valve in order to bleed the system pressure. The fuel connections are now safe for servicing.
Drain any fuel remaining in gauge into an approved container.

If you don't have a use of the tool then use a shop rag and put over the valve stem in the pressure rail and use a pencil to put the valve in to relieve the pressure. the shop towels will absorb the fuel.
The pressure is now released as long as you do not turn the key on. There will be a little fuel coming from the lines from the fuel filter.

Your vehicle could have either a canister type filter which in that case you just put a new canister filter on. If you have a filter cartridge then the take the filter cartridge out and lube the o-ring with some oil and install. Turn the filter canister 3/4 of a turn after contacting the gasket. Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

OBD-II code P2120 What does it mean? Throttle/Pedal Position Sensor/Switch "D" Circuit

This condition may have to do with the ignition key or ignition switch. You Yukon should have the VTD. So if the key is defective then the car wont start. Do you have another key you could try?
You could also have a problem with your ignition switch. Check to see if you have power at the fuse. If not the suspect a faulty ignition switch.
Hope that helps, let me know thanks.

Tire vibration can be caused by a few things. Here's what to check:
1. Check the tire inflation. Make sure it's at the recommended pressure.
2. Have a local tire shop check your tire balance. If a tire is out of balance you'll notice the vibration at speeds above 50mph.
3.Wheel alignment. If the alignment is out, the tire will show uneven wear and can cause vibration also.
4. If a front wheel bearing is going out, it can cause vibration, but since your car is only 5-6 years old, this probably isn't the case.
Hope this helps you narrow it down.
Best of success!

there is not a seperate fuse for the license plate light . If your other runnung lights and parking lights work its not a fuse. Look at the connections inside the light socket they can become corroded or its a broken wire if its not the bulb itself. I assume you have tried more than one. Remember even a new part can be defective.

might have to turn it over for quite a while for the fuel pump to prime itself .

check the lead wire to s terminal on the starter, it should have voltage with the key on start

Under the hood in the fuse box you need to check two fuses, PCM1 and PCM B. If both of those are fine the next step is to look at the right side of the engine along the fuel rail. Tiy;ll see a black cap. Remove the cap and turn the key to the on position and then press the valve inside to see if there's any fuel coming out.

It's quite possible the fuel pump burned up when you ran out of fuel. When you turn the key to the on position can you hear the pump activate and send the fuel to the injectors for initial start?

It is possible that the battery was the problem due to low voltage. I would keep an eye on the problem and make notes on any conditions if the problem reoccurs. The speedometer head or connections etc. could be a cause, but since problem seems fine now all you can do is watch to see if it happens again. Unfortunatly when a problem is not happening it is very hard to repair or find why it happened. That is why any info on when or how would be helpful even though it may not seem so.

ok you need to find out if it has a fuel cutout switch also know as a mercury switch or it is controlled by the computer on the newer ones so have the computer checked

if your engine starts up and dies right away the you probably have a fuel pump problem and the service ride control mean that your air ride compressor has gone bad just turn your key to the on position and wait about 30 seconds you will here buzzing from the left rear wheel area if the compressor is working

your car is junk

I'll assume this is for your heating and ac. There is a rheostat that burns out from excessive voltage. Take it in and have it replaced, should be relatively inexpensive.
