I am about to order and replace the multifunction switch, but wanted to know if anyone else has ever had or heard of this. If so, what was the fix?
If I push my horn, the side mirror turn signals flash (one flash for each push).

Any ideas?
Your feedback/suggestions are much appreciated!!!

 

That's what I was afraid of. I have a "unique" issue. Well, I replaced the rear wiper switch (different issue) and now when I push the horn or "flick" the brights, the rear wiper comes on (intermittent (3 swipes, then done)).

Anyone have any ideas?

Thanks again!

 

I would double check that it was the right wiper switch. I had a 64 pontiac that they changed the tail light bulb (with the wrong one)and then i pushed the horn and the the radio would come on and a bunch of other stuff went haywire. it took a good dealer mechanic 4 hours to find it. it didn't cost me anything because the mechanic thought it was a good learning lesson.
