Hi all, I searched for this problem but haven't seen any reports of it.

My AC/Heater blower stuck today on high (level 4). It doesn't change, even if I turn it to 0 (off). It has never done this prior to today.

Does anybody have any ideas or suggestions?

 

My guess would be a faulty fan speed switch.

 

Thanks for the feedback. The switch was the problem. Got a replacement from the dealer, and replaced it myself. Pretty simple job

 

I think my problem has also been resolved, i will also replace the switch and won't consider to hire an expert for doing https://www.google.com/maps/place/Budget+Air+Conditioning+%26+Heating,+Inc./@33.8114236,-118.1789454,8z/data=!4m2!3m1!1s0x0:0x466288eaa15fb8eb?sa=X&ved=2ahUKEwjZ_6Oa6PPkAhUYOSsKHepRATEQ_BIwCnoECA0QCA .
