I finished a successful 500 miles road trip with the A/C blasting through up to 108f temperatures. A couple days later I go to turn my HVAC system On and the rear blower won't turn on. The power button on the rear blower just cycles the OFF message on the screen. Next it turns out the A/C lines are hot and we have no cold air. Long commute home with windows rolled down in 89 degree temps. Turn off the car, without unplugging battery, and remove all HVAC fuses including the solid state BIG one. None are blown. Turn the car back to ON position with motor off, give it a minute or two, external temperature reading 117f, ouch those are some hot engine temps, coolant at 190. Turn on car, rear blower and cold A/C is back to normal. All the light bulbs are working, I thought that would cause the HVAC to fail as a "reminder" but nope.
What does this mean? Where did this gremlin come from?
