Initial problem a couple years ago was HVAC would occasionally spontaneously start blowing full hot when AC was on.
I found stopping and turning off ignition would correct this until next sporadic occurrence. Lived with this for a while figuring heater HVAC control replacement would eventually fix.
Last summer noticed this was no longer occurring, but was hearing occasional series of "ticks" from vicinity of HVAC control, and then found driver side would not produce heat when set to full heat, although pass side was normal.
Replaced HVAC control and since heard no more "ticks", but driver side still does not produce heat.
Followed what I thought to be the power off reset procedure (ign off > pull fuse > wait > install fuse > wait > start engine > try controls --- possibly did not get it right), but no change.
These symptoms don't fully match anything I've seen posted in this regard. Any suggestions?
