My ac comes on but want blow cool air out
My ABS light and parking brake light only come on when my blower is turned to 1,2,3,or 4 and the blower wont work(no air). But if my blower is turned to 0 both lights turn off. If i turn the blower to speed 5 the blower pumps at max like normal and both lights turn off. Brake fluid level is good and the A/C works ice cold(usual) only when blower works at level 5. Help please?
the casister vent solenoid and the vent valve was replaced. I now have a non-working gas gage, could this have been affected by the replacement of the eev solenoid?

We have had this problem for over a year. It has been to our trusted GMC dealer shop several times with no resolution of the problem. VERY FRUSRATING!! Help, please!
The A/C works perfectly fine. Yet when switching over to the heater nothing but room temp air blows out. This problem started at about 90,000 miles. Im planning on selling the truck soon and i would like to get it fixed. It has been freezing winters with the heater not working. I have had to replace the fan once before due to the wire harness connectors melting to the fan. Could that have started the problem? Or is it the A/C / Heater actuator not working? The truck now has 110,000 miles on her.

when shifting into 4 wheel drive I can hear the actuator motor shift into 4 wheel then the actuator immediately shifts back out. Then after two attempts it stops all together.
When I start the engine it displays in park as it should. but when I shift into Drive is displays 3. If I shift into first or second it still stays on third. In neutral of reverse nothing is highlighted. As I said the tranny seems to be shifting ok. Any ideas?
