I have 1998 gmc sierra 3500. The two buttons for recirc and a/c stop working and the defrost floor selector quits working. Bought a junkyard panel and it worked until I charged the a/c system. The compressor kicked on for three short bursts and then the lights went out and the level selector quit working on the "new" control panel. What could be burning up the control panel, no fuses are blowing and the relay is fine. Fan speed works and temp select, just not a/c, recirc or the level selector. Stumped.
have the same problem?
