AC Will Not Engage
So my HVAC system has been acting 'funny' last few months. Sometimes when I start the car it doesn't work (it turns on and looks ok, but changing the fan speed, vents, temp, etc. does not work - it shows the changes on the LCD but does not apply them) - I turn off and on the car and then it's fine again.
Now however, I have a different problem that a restart will not fix.
HVAC Unit turns on fine, I can regulate the temp, all functions work, except the AC. When I press the AC button it turns green, but compressor does not engage, RPMs do not kick up. It's like it isn't doing anything.
Any ideas on what this can be? I reseated all the HVAC connections on the back of the unit, it did not help. I also disconnected the battery for 15+ minutes, did not help.
