Does my radio cd player have a 4 or6 speaker system GM part no 15295371 is 05 GMC Sierra 2500

SOURCE: 2007 gmc sierra 2500 IAT sensor

Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

Problem with Diesel Fuel System. Gmc 2002 duramax 2500 HD 4x4 will start 

SOURCE: I have a 2003 GMC Sierra 1500 and it has a factory

you might have to take it to the dealership to have the radio reprogramed. it should only cost 40 bucks. these radios are very tempermental and have a mind of their own sometimes. My profesional recomendation would be to have an aftermarket cd player in. they are much nicer and have way better quality than the factory radio's

SOURCE: 4 wheel drive will not engage on my 1989 gmc

actually that first soultion is wrong it is correct on smaller pickups but on the full size pick ups they use a differnet sytem
there a electric actuator on front axle
there be two elctrical plugs on front axle u want the bigger of the two other one is just to turn the 4 wheel drive light on
un plug actuator then remove actuator after it removed plug it back in but leave it out of axle turn key on and shift down to 4 wheel drive the actuator should move out if it dont that your problem if i does move this isnt your problem it either the tranfer case or in front axle
