My electrical goodies only work sometimes. They all work or none of them work. They include the auto lamps, auto dimming rear view mirror, ABS (the light pops on and my traction control button disables. Comes back on when I turn off the car and start it again), and my overdrive button. Is there a good chance this is my wiring harness? And if so, where can I get another. I heard somewhere that they're getting scarce and can cost a pretty penny.

Would you happen to know how I can test this? Since it is intermittent can I test it when it is not functioning vs when it is?

Also, I've heard that the automatic climate control can affect the electronics in these cars for some reason. Maybe that could have something to do with it?

might also want to check the Vehicle speed sensors, they cause the above mentioned problems as well.
