Cabin Fan Blower for AC and Heater

My cabin fan will only run on hi. Anyone know what to look for on this? I took the face plate off and look at the connectors. Reset them but still no luck.

The resistor needs to be replaced.
Try a search on "resistor" and fan or blower-there are few threads on doing this. If I recall, it is labor intensive due to its location...

Try this one..

Mine was replaced by the Dealer...while still under warranty. They told me that they have seen a LOT of defective AC - Heater cabin fans.

Make sure you check your cabin air filter to see it needs to be replaced that is the #1 cause of why the blower motor resistors go bad.
