It's totally rebuildable. The combination switch includes: Hazard light sw, Turn signal sw, Windshield wipers & washer sw and of course the headlight sw This rebuild is for folks having trouble with either their turn signal switch, headlight switch & dimmer or wipers :frustration: The only thing that is a seperate switch is the windshield washer - it's up in the stalk and not covered by the procedure below. How to: Remove the steering wheel [see my photo gallery- IMG_0974 to see if your steering wheel is the same]. Start by removing top horn button cover - it's clipped on with some really firm clips. *** applies to 1991 models, other steering wheels might be different***** Remove nut/ washer from steering column. Use puller to remove S. wheel from column. Remove plastic shroud from around steering column - there is two pieces upper & lower. As well as some screws there is also some alignment clips that hold it together. Disconnect all the plugs that run to the combination switch near the base of the steering column. There's a ty wrap around the main wiring harness - don't have to cut it, it's the removable kind. There are 2 or 3 screws that hold the combination switch to the steering column, remove these and it should slide right off. Sometimes the "cam" for the turn signal holds it up a bit so be patient. On work bench turn combination switch upsides down. Remove all the screws that hold the circuit board on EXCEPT FOR the last one. There is some spring loaded brass contacts in behind that do the switching - they will go to God knows where if given the chance. Now that you know this you can remove the last screw just don't say I didn't warn you Clean up all the contacts with some electrical switch cleaner NOT brake cleaner - some brands are not friendly to these parts. Relube the contacts with some light grease. Reassemble the combination switch. Now that switch is back together you can clean the "cam" for turn signal, remove old lube both inside and out. I recommend a light smear of lube on the inside and out of the cam. Reverse the above list and you should be good to go. This is a repost from another thread that I did just so it would be here for reference.
