since then this happened.
i drove to the store and went in shopping with the keys in my pocket.
when I got back in the car the vent was blowing air.
This can,t just be the vent motor.
BTW= in the past I posted= when climbing a high bridge or hill the vent fan will temporary stop blowing.
As I ride over the crest and head down it starts back up.
One of the good automotive forums guys said it,s probly the vacuum ball in the left front fender. or some vacuum line near the passenger firewall.
