Has anyone ever taken apart the Auto heat controller on the tunnel that controls the heater flaps and has the 3 speed/ defrost fan. I have a situation were I get the first two speeds but when I crank it to high speed defrost it runs for a couple of seconds and then the fan stops. Fuses are Ok, system resets quickly to the first two speeds but the high speed issue remains... Am i looking at a variable resistor that is failing or a dial potentiometer failure. I had a situation about a year ago where I kept blowing fuses and when I removed the knee well fans I found that the rats cage on one of the fans was dragging on the housing and froze the motor armature thus blowing a fuse.

Anyone have the full schematic for the control module?

Thanks
