you really hate that diagram i gave you dont you?


it shows you exactly what's on that fuse: basically anything that's a BLUE wire.


I doubt it's the heater control unit, as that's just power for the light bulb.

so things you can try unplugging one at a time:

a/c relay
wiper switch
wiper motor
abs module (under steering column)
airbag control module

 

Brain you where so right thanks for the idea and the diagram.
It was removing the wiper fuse in the top right corner on the underdash fuse box that did the trick.
Joe thank you for your help too. Its nice to have experts with experience to lean on.

I hope this post help some other person with a similiar problem down the road because the road from the symptoms to the solution was a long one.
