It sounds like you have a fan clutch problem. You can test this by letting the truck idle, place a fan in front of the radiator, on high and see if it cools better. Good luck.

I have a 2002 gmc 1500 sierra problem is my ac is only coming out of the defroster and the lower floor vents even when I have the control unit setting on the foward vents on the dash.What could be causing...

Under the dash is the center is a actuator motor attached to the heat and ac ducts that control where the air is directed be sure it is working, sounds as if it is not, You can replace the motor yourself if it is needed. If memory serves me correctly the motor just screws into the duct work and has an arm on it to move the door. Hope this helps.

While running down the street the ac works great. When I stop for a stop light the ac quits working and blows warm air. When the light turns green and I start moving again the ac works great.

two things are possible here. is the a/c fan working or not. this would mean you are not getting the cooling while setting still but are while moving. also you could be low on freon charge and this will happen. if this helps please reply and good luck

I have a 2002 GMC sierra 1500. Instrument Lights Not Working

When dash lights don't work odds are the tail lights don't work either.Sounds like Dimmer switch may be a problem.

Brake pedal vibrates while braking and doesent stop right away

There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

2002 dodge ram 1500 ac works on hi only . works great on hi only

Hi, this problem isn`t to bad.Replace the blower resister,or resister module,located in the blower box,could be mounted outside under hood in firewall(near windshield)passengers side.It also could be mounted under dash very near blower in blower box,for this resister has to be cooled by the blower motor.This resister is the speeds for your blower.
