Does anyone have a tutorial on how to remove the multi-function switch? I have the, seemingly, common issue of wipers not turning off. I bought the new switch, but don't see how to get it out without taking the whole steering wheel off. I can't get to the screws on it at all. I got the plastic covers off, but can't see how to get the switch out.

 

Shortly after I posted, I found another thread with steps from a couple years ago. I got it taken care of. Old part was covered in corrosion on the connector that plugs into the column. Took a bit of work to clean the column board to help prevent future failure. Anyone know how wetness is getting in there to cause corrosion?

 

Hard to say about the moisture. I have it in all kinds of places it shouldn't be- inside scab doors, oozing down from the tops of the windshield and back glasses, etc.

 

that's what makes it odd. There are no signs of moisture oozing in. Only on this connector itself. Nothing around. A friend suspects that maybe the assembly line worker dripped sweat on it during assembly. That would make sense for it to take 2 years to corrode.

 

How did you clean the corrosion from the connector?

 

I used 99% isopropyl alcohol and a mini brass wire brush for the board. For the connector I used the alcohol and an acid brush to get into the contacts. It takes a lot of time but with the correct electronics tools, you can get in there.
