Hiya Phil,

Right now I'm looking at changing my multifunction switch as well. My left turn signals quit working, and my high beams no longer work as well.

Looking at the service manual it seems it is required to remove the steering wheel. I haven't personally read anything about the headlight switch, however.

Here are the relevant pages out of the 3337 page service manual to replace the multifunction switch. The service manual can be found here .
