Fixing the Dome light problems
Posted 04 October 2013 - 09:17 PM
I'm not sure if I'm the only one with this problem, but it couldn't hurt to help others with the same problem. The problem I'm addressing would be the dome light buttons. When you go to turn on the map light, you have to fiddle with the button to get it to work. Maybe those buttons don't work at all. Well, here's how to fix it. First, you take the dome light out. I didn't take pictures of this process, but you basically take the cover off toward the front of the dome light, and there are three screws holding the rear-view. Take those out, and take the two out that fasten the dome light in. The dome light will come out if you slide it forward. Make sure not to rip the connector off of the wiring harness Disconnect the harness, and pull your dome light out. There will be two screws holding the reflector in, and two screws holding the button assembly in. Take those four out, and then gently take it all apart. I left my ground cable in mainly because you can pull most everything out without removing that. Then, there are four screws in the button assembly.
Take those out, and then you have to pry it to get this.
Take note of these notches in the board, they'll try to hinder your progress or scare you.
You should have this now.
Those 3 center jumpers come out, make sure not to lose those little springs, you'll hate life after that!
Mmmm take a look at that delicious 26-year-old di-electric grease.
I took 2000 grit sand paper and rubbed the jumpers on it.
Compare the one on the right to the left two, it looks significantly better after light sanding.
Now, this sounds tricky, but I promise, it's not. To get the map light buttons out, you have to press the button, and the pull the contact out.
I cleaned one lightly with sandpaper, here's it next to a dirty one.
After the sandpaper, I used an alcohol prep pad to get the old grease off. Then I put that back together.
Alll shiny Then I wiped that gross board down with the same prep pad, it should come out nice and shiny:
I sanded in after to make sure I was at bare metal.
Then I applied new di-electric grease to the board. It doesn't take a ton, be gentle with it. We don't want any of the grease touching each other and causing a short.
Re-assembly is exactly the way it came apart. Put it all together, and give yourself a pat on the back, because now all of your dome light buttons work!

Oh, and good write up too....

The greese will help protect the contacts, but sanded contacts will "burn up" faster than smooth contacts.
I learned this from the mechanical arcade industry.
Very helpful writeup though.
