Question about 2002 GMC Sierra

1 Answer

Floor vent problem

I have a 2002 GMC Sierra SLE pickup. The floor vents have stopped opening up so there is no air going to the floor. I had a 1999 Chevy pickup that did the same thing. With both trucks the a/c indicator light went out then the recirculate air light went out. After these things happened, the floor vents stopped working when the knob was turned. With this happening, do you think it is the whole climate control assembly or a motor to the floor vent has gone out. With both trucks having the same symptoms, I am leaning toward the control. Please help before I have to spend a lot of cash eliminating faults.

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.

Im only getting ac coming out of the defrost vents and lower floor vents>

This is most likely a blend door issue either in the climate control or within the blend door. Either way the door is stuck in a position that is only allowing it to go to defrost or floor vent. It will need to be further diagnosed by a qualified technician to determine which one is the culprit,

Usually a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

99 GMC Sierra 4.8 1/2 ton 2 wheel drive new body style ac does not blow cold air from the front vents on the dash? Still get some cold air from bottom by floor vents,

if both vents are blowing air in general then you may need to get your air conditioner recharged, but if the front vents aren't blowing at all then you may just have a jammed vent flap and you can fix that from under the hood next to the blower motor. check you rowners maual for the exact location

A/C not blowing thru vents just defroster and floor

It is a vent door actuator motor on top of the blower box,the dash has to be removed and set in the seats to replace the actuator motor.Cost for the part is about 50.00 dollars

2002 gmc sierra blows Hot air thru ac vent on drivers side. Whats going on? Setings are set for cold air and we are getting cold air thru vents on passenger side.

We have this fairly often on our gm fleet with dual air controls. Replace the actuator and you will be good again (for a while!)
