Well, I have been looking around everywhere for a good price on a brand new headlight combination switch ever since mine started acting up. Cheapest one I could find was $120 after shipping at Acura OEM parts online.
Me being poor decided to go looking around at used ones on Ebay and they are still overpriced and will probably have the same problems eventually over time.
Well, me being the really adventurous type with the electrical repairs I decided to basically rebuild the combination switch much like I did my electrical slider for the automatic transmission shifter. Almost everyone told me that it cannot be taken apart and cleaned, just to buy a new one.
Well, those people were totally wrong. You can recondition the combination switch the same way you do the electronic shifter mechanism. The only thing is, well, you better have an easy touch and know how to put everything back together. These things have more than twice as many parts that need totally cleaned and re greased with the dielectric grease. You have to take the entire assembly apart very carefully, with the same kind of feel you would use if you were a surgeon. Clean all the electrical contacts the same way you do the electrical shifter mechanisms, using high grade rubbing alcohol. Also you must scrape all the contact points using a good scratcher to make the contacts shiny.
Let me repeat this again: Dont break anything, dont loose anything, and clean and shine every bit of metal on metal contacts. After you do that make sure that you put new dielectric grease on the contacts. Then reassemble it back the same way it came apart. Check how the switch works in all ways before re installing it back into the car. If it dont seem right, dont put it back in, you could start an electrical fire if you put power to it if reassembled wrong.
But anyways, if you can do this without fucking anything up, you will save yourself over $100 for a new part.
