AC/Heater Blower, no Blow?
I got into the car last night and suddenly the blower for the AC/Htr did not work. I checked all the other controls on the AC control unit and I believe they are working as I can hear the vents moving to different configurations as I ran through the controls. I wonder if the Potentiometer on the AC control unit that controls the blower is on the fritz? I already had one of these control units replaced via warranty, less than 3 months ago, looks like another one. This picked the wrong time to go too, I was caught in a thunderstorm and the windows got really fogged up and it too a while for them to clear-up.
Anyone else had this issue?

Maybe not a "technical" answer ,but try to "slap" it with your hand (right under your dashboard).
If he starts running , than it is your blower motor .

I believe the blower is above the front foot well area on the passenger side. It quit on my twice last winter due to ice build-up... gave it the magically slap to resuscitate back to life.

Gee took it in before I saw your responses and the dealer is ordering me another Heater/AC control unit, so we will see what happens when it arrives.

Well i found out they ordered a blower and a relay as they apparently failed not my AC/HTR control unit - I do like that. As i would have been expecting to have continued issues with that control unit if the current one needed to be replaced.
