Hi, I am new to this forum site and new owner of a 2003 Envoy. For now, I only know of one problem that I need some help with.
Question- The electronic climate control setting is stuck at 50 degrees. Never changes. What will I have to check or replace to fix this problem?
thanks, JH

But first try a freebie. Push front defrost, rear defrost and mode switches at same time and this should reset the temp. If this doesn't work, then get a new sensor.
