Question about 2001 GMC Sierra Crew Cab
2001 GMC Sierra. Heater is stuck on full heat. It is not responding when I turn the dial to make colder. It does not respond when I turn the A/C on. How can I fix this?
Did you ever find a solution to this problem? My 2001 Sierra does the same thing; if I turn on the heat to full hot it remains stuck for a while. Sometimes it sticks for a couple of minutes, other times it sticks for a couple of days. As long as I don't turn it fully to hot though, it doesn't stick. It has gotten worse recently.

If you dont hear a switch over when you turn dial the system probly needs a charge possibly low pressure.if its just the dial knob need to open the panel and see if its making contact while turning knob see if it switches.
