My blower quits blowing after driving for a while. Last fall (for $500+) the dealer replaced the electronic control (in the dash), but that was actually a shot in the dark and it didn't work. The control on the dash shows the blower should be blowing full force, yet there is no air coming out anywhere after a while. It seems to happen after I've driven it for a while on the highway at 70 mph - about thirty minutes or so. I drove it for more than an hour at less than 60 mph without a problem the other day. It seems to misbehave intermittently, but mostly after driving on the Interstate. Has anyone else experienced this problem? Could there possibly be a damper of some sort that is closing at the wrong time when it heats up? A friend suggested some kind of solenoid mis-firing? (Bear with me, please, I am of the female persuasion and not at all mechanically inclined.) When I put the car in park and then start up again, the blower will start blowing full-force. It will also start up again properly after the car has been shut off. The car is going to the dealer on April 12th to see if they can figure it out, but I found this forum online and was hoping someone here could give me some suggestions. The dealer's next "plan" is to replace the blower motor, with no guarantee that it will fix the problem. I've gotten quite frustrated especially since I live in the Midwest and now is the time to be driving with the top down and the heater on! Of course, the dealer hasn't been able to recreate the problem! I told them THIS time I'm not going to shut it off OR put it in park ... before they see that I haven't totally lost my mind! Any possible solutions from this forum? Thanks much for any possible clues ...
