Hi,
Okay, is there anything other that is not working? I ask because I just went through the wiring schematics for the headlamps, tail lamps, and wipers and there is only on common ground for them, the multi function switch on the steering column. If there is something different happening, then my thoughts of that being the problem will change.
All of the items you mentioned have separate fuses as well as grounds, so I have a feeling it is the actual switch.
The directions for replacement are in the two attached pics and somewhat vague. If you decide to replace it and run into trouble, let me know.
Joe
