Question about 2002 GMC Sierra

1 Answer

Cold feet 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.

    What would the chances be that the same sequence of events happened on two different vehicles. I looked the best that I could under there and didn't see anything out of the ordinary.

Make sure no one has kicked the vacuum hoses off on the passenger side under the dash . look under there and see if all hoses are still connected properly ..

I have 2006 GMC Sierra SLE 4WD 5.3 liter and my engine light comes on giving me the code PO449 Evaporative Emission Control System Vent Valve/ Solenoid Circuit Malfuction. What could cause this code to...

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.
