Need To Clean Your Side Mirror Switch?
MVS Contributor firestix: First off I read some post that said you had to take the door off to get the switch out. Not for me. I simply pulled it out with my fingernail. You might want to pry it out with a cloth covered screwdriver.
Here it is out and flopping about. You might want to note how clean the switch looks compared to the window switches. This was the topic of another post. My secret to cleaning is called butcher’s speedball, and a few cotton swabs. The “sticky gunk” removes quite easily with the aforementioned products.
I took pictures out of order so forgive the fact these are already out of the car… you’ll have to do this in the car. Using a precision flat head screwdriver I gently pried up the edge and got it over the nubs holding the switch together.
Watch that you don’t loose the white plastic contact bits when you pull the switch apart. Here’s what you will be looking at once you get the switch apart.
And the other bit still attached to the door. I know the picture is blurry, and the picture really doesn’t do the process justice but if you look at the left side 4 way contacts they have been cleaned with a standard pencil eraser. I saw many a post suggesting using fine grit sanding paper but the eraser cleans the contacts and will not damage the PC board coating. I also used the eraser to clean the contacts on the switch side. then after cleaning all the contacts I put on a very thin layer of dielectric grease. (still wondering if that was the proper grease choice.)
On the other side of the PC board is a connector which might be of use to you if you are doing a switch replacement, or pulling the PC board out for more extreme work.
Now reverse the order being careful of your plastic electrical contact bits. Ensure they don’t go falling out of place. Snap the switch back together and re-install it into the door.
