Hello,

If you can attach a close up photo of the wiring diagram glued inside the blower compartment, taken from close up, and straight on... very well lit, and very well focused, I can coach you on further diagnosis or repair if you like.

Use the paper clip icon at the right end of the tool bar to attach the photo.

We can go from there.
