T660 heater fan stops for hours and windows fog up.

Mine is in the fuse box, it has breaker in place of fuses. Breakers are made to kick out. But when it kicks out enough. It gets weak,and will get hot enough to burn your fingers when you touch it. I found mine when it burned my fingers. Will use a cheap infra heat gun temper gauge from now own.

 

That li'l stubby one was my culprit. No, it's not the same size as the others because I got it at Advance Auto. The blades are a bit shorter, too, but it works just fine.
