I look at a diagram and it shows a box with 5 wires coming out of it, but when you look at the actual box there is about a 100 wires in it. It looks like there is no way to actually get to the metal leads on the box/control modual.
do you need a hand held scanner to fix these problems?
Do you need to be a genius?
No wonder the dealerships get about a hundred dollars an hour.
My fans don't work.
