W123 visor wiring - PeachParts Mercedes-Benz Forum

hangit · #1 09-10-2007, 02:15 PM

Is there any way to easily check/replace the wiring in the visor that powers the vanity mirror light? I have power to the visor clip, the contacts have been cleaned, but no power in the wires. My next thought is to wire a AA size twelve volt battery into the circuit. Thanks.

Are you saying;
You have power to the clips (mounted on the windscreen frame) but no power from the end of visor to light bulb socket.

Are you measuring voltage with visor clipped into place? It is part of the connection that completes circuit. The frame at the upper left corner of mine has just broken, door needs to be in just the right position to light up.

I have voltage at the clip without the visor in place. No voltage in wires with visor clipped in and rotated so contact points are engaged.

Slightly off topic here. my '77 doesn't have lights, just a mirror on the passenger visor. The visors are also full of crumbled foam. What year W123's had lighted vanity mirrors? I don't have much use for them, but the wife would probably love to have them, since even her lowly Kia has them. If I'm replacing them, I may as well update.

Now my wife doesn`t like the lighted visor. she says that it blinds her. the light needs to be in a different location.
If I used makeup I would understand

There is really no way you can totally replace the wires to the contact point with out cutting into the vinyl. You can peel the mirror/light case off and reglue it back. But that is about all you can do without doing too much damage to the visor.

I think 83 was the first year for them.

Thanks DV. That's what I was afraid would have to be done.

Just post a WTB (want to buy) in the parts section with color you are looking for. Someone will have one.

Folks, I purchased the lighted mirror insert for my visors in my 1983 300D, but was wondering what type of glue to use to glue the mirror insert into the visor? Down here in the Houston heat, it has to be pretty sturdy to not come undone. Any help and suggestions are greatly appreciated! Thanks in advance!

Use hot glue. seem to hold ok.

Just read my post#6, that was 9-07. since then I replaced both of my mirrors. We have the black interior, but haven`t found anything in black. but there was a w126 with dark blue interior at the PNP.

I removed both mirrors, cut the wires as long as possible. then removed the morrors from my old black visors. cut those wires short so would have plenty of wire to work with.

The 123 has the light switch in the corner and was broken on both of my old ones. seem like it was a cheap design. but the 126 mirrors have the switch in the center and in a little micro switch. much better.

Along the edge of the case are three little tabs that hold the two halves together, push them in and lift the mirror and the flip up door part and the two halves will separate.

The glue on our old ones had given away a long time ago, so they just lifted out. I used hot glue to attach the vinal along the inside edge of the visor. originally when new the mirror held everything in tight.

get everything cleaned up, old glue etc... then solder the wires together. and some heatshrink tubing over the solder joint.

there are six or so holes in the back half of the case, I marked where the holes lined up with a felt tip pen. then used hot glue on the marks. set the case into the visor and hold it down until the glue cools off. might have to add a little on the top side.

The W126 mirrors have an improvement to the light bulbs. the metal reflector curves over the bulb so now my wife doesn`t get blinded when she uses it. sort of a defused light.

snap in the top half of the mirror to the bottom half, and mount back on the vehicle.

Now I said I used dark blue with my black visors, when they are pulled down it is not noticeable unless looking for it.

Since you have power to the clip, the only thing that makes sense here is your visor mounting screws are not supplying the proper ground. Are they stripped?

Or you may have a pinched/severed wire under the mirror housing. Of course you would have to pry the mirror housing out of the visor to check.

Is it just one visor that doesn`t light up? or both? have you checked the bulbs?

I don`t recommend to use Hot Glue as I mentioned in the above post.

If you live in a cooler area, it might be ok. but, if you live where it is hot, and the car is closed up. the glue will not hold, especially if the visor is in the down position. the glue will soften up to the point the weight of the mirror will pull it out. you will come back to your car with the mirror hanging by the wires.

Plan "B" for me, was to go down to the local Glass shop, and have them give it a squirt in the corners with that urethane glass sealer they use.
It has held very well for the past 3 or so years.

stumbled across this old thread, and thought I better up date my info.
