I've been using the heat quit a bit lately as the weather has gotten colder and today was no different. It was working fine when I cut the truck off to go in for lunch. When I came back out, no fan. The heat still works and I can feel hot air coming out of the vents, just no fan. I notice that when I move the control from the 3 to 4 position that I hear a click from under the passenger side dash. I checked fuses and found no problems. Any idea what the problem is, what caused it, or how to fix it? Thank goodness for my heated seats!

Good work wtfturner

 

Thanks Wil. I did search but didn't find that one. I guess I know what my project is for the day. I wish I was home in the garage in TX instead of out in the weather in GA for this one! Thanks again. I'll post my progress later.
