So my wifes ac started a new issue. It turn on full speed (level 7) then over about 5 mins max slowly turns down to lower then low speeds. It stays cool, just doesnt blow. I've done some searching and found it could be the blower or resistor.

But the resistor is a master hide and seeker.....

Any help is gladly accepted.

 

auto hvac or manual?
automatic systems will lower the blower speed as the temp approaches the set temperature. auto systems use the module to control the fan speed. if you want to disable auto control turn the system to max or shut off the auto mode
