Followup:
The first time I started the car today, the blower works fine!
I did not do anything before I started the car.....
Then it's getting wired...
The second time I start the car (abort 1.5 hrs after the 1st time).
The blower wont blow at the beginning.
Then I turn it on high wind (was on low), it started to work.
It doesn't go high wind right away, the speed go up slowly, I finally gets high wind after about 1/2 minutes or so.
I still think there's a problem, but don't know what.....
Any ideas?
