On my 05 Impala I can momentarily turn on the hi beams by pulling the multifunction lever, but when I let go, the lo beams come back on. On my gf's 06 Monte Carlo, she can do the same thing, but if she pushes the lever forward, the hi beams stay on. On my car, the lever does not go forward, & I don't want to push too hard & break something. Is this how all 05's are, or is this a characteristic of a 9C3 car? GARY
When I pull on the lever, the hi beams do come on, but they won't stay on, as the lever is spring loaded, & returns to the lo beam position. I really don't mind, as I don't drive with the hi beams on. As long as I can flash them on, that's OK. Thanks again. GARY
dont be surprised if the high beams dont stay on eventually. I had the MFS go on my 02LS and it was same as yours, I didnt get it fixed and eventually the high beams were the only ones working. It finally clicked and stayed.
Mine went out recently on my 02LS, and it left me with no low beams or high beams at all..
That is precisely the reason it needs to be addressed sooner rather than later. When my low beams went out entirely, I was able to get them to fire back up (at least temporarily) by jiggling the MFS. Not exactly an ideal solution.
Protip: If you don't know what you're doing, don't do it.
I changed the MFS on my 00 last year. It's about a 2 hour job if you realize that you have to pull the 1 pc dash face off first. The tilt wheel lever pulls right out.The lower dash panel also comes out. Then the upper and lower MFS housing can be separated to expose the switch mechanism. 3 screws and out it comes. There are 3 wiring harnesses that have to be pulled out with the switch. The biggest connector must be lined up and connected correctly because the connector pins are very fine and have a tendancy to bend if not lined up and mated correctly.A fun thing to do lying on your back in the footwell with your legs up on the seatback. But it can be done. A word of note- If the car is a keeper get the OEM part instead of aftermarket. The reason being is that GM holds patents on the switch design and for it to be reproduced there have to be changes made: translation-cheaper. It's an expensive part and your best bet is Rock Auto, or DavesDiscountParts.com if they have it.
