It does NOT have electronic air temp control. It’s a former police car which probably has a lot of idle hours on the fan while waiting for someone to do something naughty. I had not thought of that aspect. It only has 92K miles, but 43XX hours on the idle clock.
I’m hoping that the blower motor itself is not the culprit. I’ve never seen one quit suddenly like this. Usually they scream and whine in complaint for several weeks and die slowly.
I won’t have access to the car again until Monday.
