I have a 2005 Impala. The heat quit working on the driver's side but still worked on the passenger side. We replaced the blend door actuator and reset the HVAC control system. It didn't seem to fix it right away but did eventually start working off and on which made me question if there was something wrong with the control panel. I put a new control panel in without fixing the problem. We have also hooked it up to scanners with no error code showing. There was a brief time after all of this where when you would stop at a light and the heat would not work on both sides and then when you get going it would heat up again. The car is warming up but there is just no heat on either side. Any ideas? Thanks.
