(ELECTRICAL) Easy fix 4 your Headlight/Combo Switch Headaches!
 
3 Attachment(s)
I tried to take the combination switch off so that I could take it all apart and clean the contacts. I had heard that this is not easy to accomplish, but I was fed up with having to wedge a screw behind the stalk to hold it in the flash to pass position (that was the only position in which they'd work).

I ended up getting stuck and was not able to actually remove the combination switch. I got frustrated and just hosed the whole thing out with a can of contact cleaner. Turned out to be a good decision! I did not have to remove or disassemble the switch in order to get it working again.

I just sat out there for 15 minutes flipping from on to off, brights to dims, all of it. I know I made over 1000 switches and it never missed a beat. Problem solved! :D

I took lots of pictures and I'll try to post a clear set of instructions so that even my own Mother will be able to do this in five minutes. The hardest part was parting with my 10 bucks for the contact cleaner (now that I know it works, I don't feel so bad about it)

Here goes:

1. The horn removal step;

Now, the Haynes manual is going to try to tell you to pry it off with a screwdriver. But what they don't explain is that its just the rubber cap that you are removing. So in picture no.1 you can see the scrape markings where I tried like hell to pry off the metal part with 3 screws in it. The cap eventually came off, but if I had known ahead of time to picture it as if I was, well, peeling a rubber cap off, then it would have only taken a few seconds to remove.

2. Steering wheel removal;

The socket I used was a 13/16ths. It's probaby metric, but this was a perfect fit. Once this was off I just pulled side to side a couple of times and the wheel popped right off. No sweat, but make sure you don't pop yourself in the teeth when doing this.

3. Watch those ball bearings!

In photo #2 you can see the plate that covers the two ball bearings. These bearings are what holds the lever in the dim/bright positions. Make sure that the lights are in the dim position, then remove these two screws and the cover plate. In picture #3 you will see me drawing out the bearings with a magnetic screw driver. This is after you gently ease the lever into the bright position. There are springs behind these, but I just left them there because the grease held them in pretty good.

Okay, now we're almost done with the hard parts...

Step 4; Removing the stalk

Gently pull the base of the stalk toward you, then at the last part of the withdrawal process you will pull the end toward you to ease the little doohickey our of the interior. Take a look at pics 1, 2 & 3 and you'll see what I mean...

Now the fun part...

Step 5 Let the hosing begin;

First, unplug all of the electrical connections from the back of the switch even though the battery is disconnected (oh, by the way, did I tell you to pull the - cable off of the battery earlier?). I'm not sure if this is necessary, but its what I did.

Now take the $10.00 can of contact cleaner, stick the little tube into the nozzle, and hose the contacts off. I just hosed everything in there and all around. The stuff comes out at high velocity and foams a bit (don't get it in your eyes).

Next, I threw the stalk back in and moved all of the directions to work over the contacts. Then I repeated the hosing. Let dry. I hung a light from the visor to add a little heat to it, and after about 10 minutes I blew it out with a can of air (did I really say you could do this in five minutes? What was I thinking?).

The following pics show the contacts behind the stalk, and the cleaner and can of air I used.

Reassembly should be self explainatory, just put it all back together... Hope this helps someone avoid a wasted Saturday...: :D

I just worked the switch back in forth heavily in a rage one night because I had the same problem. They finally started working. I didnt even have to take anything apart.

Yeah, tried that before too. Once in a great while I could get the highbeams to come on, but not reliably...

I just took her out and aimed the headlights. I had to have them aimed really low since I was on highbeams all the time. Man, what a difference! I did the relay mod a few days ago, and now that I have the highbeams correctly aimed its simply AWESOME!! So much light....:)

I'm so happy this is fixed. One of those things that just bugged me for the longest time...
