Works on speeds 1-4 but quit working on #5. Just started Friday, after work.

Replace switch.

It may be the resistor. It's under the dash on the passenger side and has a heat sink that sits in the air duct. I had to replace mine. It's not that hard or expensive. If you can change the cabin air filter, you can probably do this job.

Weird thing is it was working on # 5 Today. Went fishing this morning and it worked fine. Friday when put on #5 the air would shut off. I was thinking maybe the switch, but wanted to post here before I do anything. Could also be the resistor.
