Fan only works on "Hi"

[Lee]

Good Morning,

I seldom use the a/c or fan in my 2013 Cougar TT.

Yesterday I noticed that when using the a/c or just the fan... it only blows at one speed no matter where the fan speed switch is set.

Anyone have any insight?

Picture of control included.

Many thanks,

Hmmmmm...maybe try sliding the temp down below ambient temp. Just a WAG. There's a lot of those going around lately.

Our Coleman Mach seemed to only run on high as well. Had it looked at on one of our warranty trips. Svc advisor said no trouble found. He had us run just the fan on low, then switch to high. There was a very slight difference. Very Slight! To us seemed like why have 2 speeds
