hi, I came across your question just now and ,this is a 2 speed fan .the fan should do this as the temperature cools in the cooling system ..the fan doesnt always run on high with the a/c on ..

Customer: replied 1 year ago.
When I have the speed control knob turned up, I expect it to be at the higher speed that I set it to.
This has only begun since I recharged the freon, and discovered that it leaked.
I was able to shoot sealant into the AC and charge it again.
After that is when my wife says the speed of the fan was clearly noticeable.

ok, I miss read that ,I see you meant the heater blower fan control ..sorry .

Hello Jazzmaster,
For clarity...
The fan that blows air into the PT, to cool the inside when the AC is on slows down after an indeterminate time. I assume its the same fan for the heater, but have not experienced the issue with the heater on yet.

if you put it on recycle air mode does it do the same thing ? I want to determine if an air flap is closing ..jazz...
