My blower for the AC or heater is intermitent. When it does work the blower speed starts off perfect and after 5 minutes it slows down and eventually stops till I shut the car off and wait about an hour and then restart it.

Posted By: carguy#1 Flag Post For Monitor Review Shop: MY CAR GUY Date: 7/12/2009 6:34:24 PM Hey Doc J., Had a similar problem/vehicle about two months ago. By passed everything and found motor would work if direct wired. Tested wiring from switch and found it to be working. at that point had to assume that controller (mounted on motor assy) was bad. Found out they were common to fail and had been redesigned. Had to replace motor and controller ($700.00+) Hope some of this helps.
