Use CRC on MAF Sensor

Okay, you should check all the bulbs make sure all are working fine. See under which conditions the lights are dim. maybe if you give a better detail, I can try to help ya out.

Its hard to tell what it is without being in the truck. But transmission issues usually involve a lack of fluid or a clogged filter. Lots of times a filter change will fix stuff like that

It means check the air pressure in you tires, you may have a soft one from a nail or such. If you have a full size spare, check that too.

Hi,
This will be caused from one of the following problems:
1. Lift-gate ajar sensors are faulty or need adjusting. Check and test these. 2. The lock solenoid needs lubricant, it maybe sticky and not able to move freely. Include and adjacent pivots from the lock solenoid. 3. The main body control module maybe faulty, test this with a Consult II diagnostic tool to check it.
The first 2 solutions you can do and also the 3rd if you have the diagnostic toll for it. Try these solutions and let me know if you need more information.
Thanks
Jason

Sound as THEFT radio system is armed; this occurs when the battery is disconnected or died or wotn have electrical voltage at radio. In the Owners Manual you could check the disarm procedure and the way to enter the unlock codes. If you dont have the manual, need to visit the GM dealer and show the VIN before to ask for this information. Remember that this lock code is unique for each vehicle ans just the dealer could send you.

Hope helps.

Mine aren't either. I have an 03 Tahoe LT with steering wheel controls. The audio controls work just fine, but not the dic controls. Can someone please advise? Thanks!

If you are referring to the door latch being in the closed position, make sure the child safety switch is in the off position and use a flat blade screwdriver to open the latch. You may need to spray some penetrating oil on the latch.

check coolant level first, then pressure test the cap and radiator to check for leaks. if this does not work, then lift the vehicle drain some coolantout of the radiator, then locate the heater hose leading to the back core, and remove these from the easiest location to reach, then take compressed air and blow in reverse flow direction to remove any blockage. then reverse install and check.

Had this problem on my 2004tahoe. there is a fan control module that is bad. The module, if i remember correctly, is inside the heat control box on the passenger side. the fan is there as well. the part is about 150? - shop around.

Check the fuse on the blower motor.

If the check engine light is On that means there is a error code got set in the cars computer.Get your car scanned at auto-zone for knowing the exact fault code.The error will indicate the exact fault causing the engine light to remain ON.At autozone service center its free to get car scanned.-------- That's it.

If the lock does not operate with all the others, then that must be referencing the electrically operated solenoid mechanism.
It could be due to mechanical binding, but has nothing to do with the door contact switch.
Instead, the most likely is the solenoid or the wires going to it, where they flex at the hinge.
Use a test light to see if the solenoid is getting current when an attempt is made to unlock the doors.
If so, then the solenoid is probably burned out.
If not, then the wire probably broke where it flexes. Move up stream to the next junction to check for current going to the solenoid, to unlock the door. If you can't find a convenient junction, then you can pierce the wire with a pin, and test it by putting the testlight on the pin.
