AC is cool and the AC Blower fan runs at high speed after a slow down, but only if you key off and restart the engine.

Of course it does not cool the car off quickly running at blower speed "slow".

I have a AC temp probe which reads about 50 F on a 90 F day.

I'm puzzled by how blower gradually slows down (in abt 1 minute) when the auto, and recirculate buttons are pushed.

I observed today that if I select the upper outlets, (not Auto), the slow down of blower speed does not occur. But today was not nearly so warm. Only about 80F.

Both cabin filters were replaced last September. The old ones that had been in the car 10 years were not very dirty, and no real improvement in air flow was noticed. I was not having the Blower slow down difficulty at that time however.

Thanks for responding.....
