Question about 2001 Chevrolet Silverado 1500

1 Answer

I have a 2001 Chevy Silverado 1500 Z71 truck. When I drive for more than 20 or 30 minutes with the heater on, it gets "stuck" and then blows only real hot air, even if I turn the air conditioner on high. The truck gets so hot in the cab that I have to pull off the road for 10 or 15 minutes to let it cool down. What can be happening?

Do you have a hot water valve out by or on the engine usually you can tell by following the heater hoses the water valve will be in line or be coming off of the engine intake manifold, it is vacuum operated older valves can stick, try that first or if you have a vacuum gauge check to see if the vacuum bleeds off you can also manually apply vacuum and feel what the heater temperature does.

2006 Chevy Silverado 1500 z71 4x4 the ac wont kick off after key is out of the ignition and it only blows hot air.


I am assuming you mean the blower will not stop with the key off.
The compressor can't run with the engine off.
I would look for a stuck blower relay.

How do I get to the heater core (through the dash_, but is it on passenger side? I am having trouble getting the bolts off. Truck is Silverado 1999 Z71 (1500).


I just replaced the heater core on my 1997 S-10. If your chevy is anything like mine, the entire dash has to come out. I recommend buying a Hayne's manual for it. Those books are life savers.
