No such thing on an electronically controlled transmission. This uses shift solenoids, not modulator valves.

My database showed lower right rear of engine block. If starter motor is there you may have to drop it, to get at the sensor. I can't see anything from here.

As tight as you can get them with a 18 inch breaker bar. I use an impact gun( 400 ft lbs) on them. If you want to be extra sure, use blue locktite on the bolts. Specs are around 135 ft lbs.

yes they can be replaced but you would have to handy and confident with a soldering iron if there isn't a small socket that the bulb fit into. Most if not all the backlighting bulbs are those clear bulbs with the blue covers over them. remove the LEDS from the twist socket without breaking the leads and they would have to be soldered directly to the circuit board like the existing bulbs.

Check your fuel filter if it needs replacement. Empty it out then connect it back. Try to start it again. Inspect the fuel filter if it filled with gasoline. Check if there is noise at the fuel tank to check if the pump is working. If it did not, inspect the fuse for your fuel pump and the relay. If both are good you may connect the fuel pump directly to the battery to see if it works. It may be a bad wiring.

It is possible that the harmonic balancer is slipping back into the timing chain cover making the scraping noise. If the vehicle has electric fans, a fan motor could be bad.

Well I was about to say you need to read the codes and fix those issues. Your truck is going into 'Limp Mode', this is indeed reduced power. The ECU is doing this to protect the engine from serious damage. You need to fix each one of those 4 error codes. Having said that, they all point to the throttle position sensor. Wnen you put your foot on the accelerator *PEDAL the sensor tell the fuel management and air management sensors, how much gas you are giving the engine. In the old days it was a cable to the carburetor, but now fuel injected and all electronic.

You can read details on the codes and how to fix here. You can also put each code with Chevrolet Tahoe into Google and look at the video tab fro how to fix.

It sounds like it just needs to be reinitialized. Turn your key to the on position with motor off and hold the up/full vent button down for at least 30 seconds or until your sunroof either clicks or goes to the full vent position. That should fix your problem.

Always disconnect the battery before performing any maintenance on the vehicle. This will prevent you smoking something important.

Your best bet , take it to a qualified repair shop . Service 4X4 light's blinking . DTC'S - diagnostic trouble code's stored in the 4X4 control module.

2004 Chevrolet... | Answered on Jan 22, 2018


Pulling code's from the 4X4 control module would point to a diagnostic procedure . Do you own a professional type scan tool that can read DTC'S - diagnostic trouble code's in the 4X4 control module ? Autozone , advance etc.... can not read these code's .
Which transfercase does it have ?
Transfer Case - BW 4482-NR4
Transfer Case - NVG 246-NP8

How many buttons for 4X4 three or four ?
The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel
The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel
When the ignition key is in the RUN position, the transfer case shift control module monitors the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria has been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly.The 4X4 system with four button shift control can set a number of DTC'S
DTC B0790
DTC B2725
DTC C0300
DTC C0305
DTC C0306
DTC C0321
DTC C0327
DTC C0359
DTC C0374
DTC C0379
DTC C0550
The three button switch can also set an store a few codes
DTC B0790
DTC B2725
DTC C0306
DTC C0327
DTC C0329
DTC C0359
DTC C0550
Without knowing if any of these DTC'S are stored can't suggest any type of repair .
