Recently my '90 Trooper decided to leave the heat/blower on all the time. Even when the AC switch is off and fan speed set to lowest, it is always on. I can however switch the fan speed switch and it speeds up, seems like it is stuck on the slowest setting.

Checked the fuse in the fuse box, it's good. Anything else? I found some old posts about peoples blowers not turning on, but my problem is it wont turn on. Thoughts?
