chances are its a sensor or a valve located around the compresor on the frame rear pass.side

you have two front collision sensors int he front. drivers and passengers. if you know which side it is then just order one from the dealer. to replace the sensor just disconnect the battery and locate the sensor, they are mounted below the rad. unbolt the bad sensor unplug connector and mount new one.. plug in connector and then reconnect battery. the airbag light will come on for the startup procedure and then once the airbag startup is passed and no problems are found the light should go out. Good luck

Open the hood looking down at the top of the radiator support you will see two metal rods that go down through the support and through the head lamp assembly. turn the l shaped top out from under the retainer and lift them up and out. Now the headlamp should be free to pull out to get to the back of the assembly.

Many autoparts stores will assist you in changing the bulb if you purchase the bulb from them. J.

Thermostat is possibly installed wrong/backwards, defective, or you have a large air bubble in the engine. After you changed the therm you must run the heater ( fan on low) to help purge extra air. Hope this helps. Good Luck

I had the same problem with my 2004 yukon. It seems all the gauges in the insturment cluster are known to go bad from 2003-2006 in GMC and Chevys. The deaerships are trying to sell you a new instrument cluster which is pretty costly if your warrenty is up. I repaired the circuit board on my insturment cluster myself and everything is working fine now. Since hearing abouth this problem I have started repairing the insturment cluster as a side business. If your vehicle is out of warrenty and your intersted shoot me an e-mail (ryanfeider@hotmial.com).

What I have done in the pass with some of my customer's when they don't want to spend that much $$ is drill a small hole 1/4" under the headlight assembly so there will be a way out for the water, very easy to do.Hope this was helpful.

IT IS IN THE SERVICE MANUAL TO REMOVE THE CABLE

2005 GMC Sierra... | Answered on Nov 29, 2009


The air bag light is activated by the sensing diagnostic module. The SDM has detected a component or wiring issue that may prevent the system from operating in the event of a crash.
Take your truck to your local Auto Zone or Advance Auto and ask them to check the vehicle for diagnostic codes. Write the codes down and respond back and we can see what the issue is.
Good luck, let me know.
Regards,
