Thanks. My scanner does a lot (including airbag system) but not electrical/hvac
Compressor cycles (I change the pressure switch) and checked pressures. Air blows warm and I wonder if it’s the blend “valves” being out of whack and mixing in hot air to get to the perceived temp on the controls.
Oddly enough, it stopped cooling and as I was checking pressures the display “died”.
When I plug the display, it lights up (at the default 75 degrees) for less than 0.5 secs. It goes dark then.
Switches work (turns on/off blower, changes blower speeds).
Guess I need to replace the control. Hate to just throw $ in hopes it fixes it.
Thanks all for the feedback. I need Yoda’s knowledge!
