ok - so I just bought a 1998 SL600 with less than 30k on the dial. I love it - its a silver arrow and has the tan interior - and I spent a year looking for it.

But the previous owner seems to have loved to hang off the rear-view mirror. Whatever cheap piece of plastic is internal to the darn thing is broken, and the mirror flops all over the place.

I spoke to my mechanic - who told me to deal with it, since a replacement is like $850 !!! So whats up with this badly designed expensive piece of engineering ? Evidently its a common problem ?

Secondly - anyone know of an aftermarket replacement ? I believe I saw an SL with a radar detector built into the rear-view mirror once - i've scoured the internet to no avail - but I wouldn't mind putting out a few dollars for something that is actually worth the money. In the meantime, wads of dollar bills are keeping the mirror relatively stable (!)

Adjusting the mirror by hand will result in the breaking little plastic gears that drive the eleectric adjustment.
I cured the looseness with a rubber seal around the post, where it attaches to the top of the mirror.
Later, I found that moving the electric adjustment forward (for mirror up) and backward (for mirror down) slowly, took the play out of the mirror! It was never like new, but it no longer flopped around. Good luck. rg

Internally, the mirror is secured to its base with a pair of metal clips. The clips are retained by plastic tabs molded into the frame around the mirror. The clips break too easily; and when they do, the mirror wobbles.

I have repaired two of these mirrors. In one case, the broken plastic tab was loose in the mirror, and I simply epoxied it back into place. But with the other broken mirror it was gone. In that case I straightened the end of the clip (the end is bent 90-degrees to engage the plastic tab), heated it with a soldering iron, and pushed it into the plastic where the retaining tab had broken so that it was anchored in the frame. If you were to take yours apart, then I think you would see what I mean.

I also have repaired this mirror. I'd consider disassembling the black, 2-motor assembly from the mirror itself and epoxy-ing the base to the mirror. I don't think those plastic/metal clip setups are long for this world. Now, I'm solid and wiggle free (the mirror, not me, actually)

HTH,

Dealer fixed mine, I will take a picture tomorrow and show you how they did it. They said the replacement mirror was too expensive and their fix works. After two years I still agree with them that it does.

he has a 98, pretty sure he doesn't have a power rear view mirror.

I have the same problem with my 97, I just stuck a dime in between. it doesn't fix it, but it makes it a little better. I have yet to remove it and investigate to try and come up with a solution.

To those who swear by Mercedes engineering in all things, I've always wanted to point to the R129 rear view mirror as an example of very poor Mercedes engineering. The one in my '96 SL600 flopped around like crazy. I was able to disassemble it and sandwich a rubber pad between the mirror itself and the mounting bracket. Required 3 hands to reassemble, but it is far, far better than it was - not perfect, just better. And I saved a ton of money!

I have had my SL500 for 2 weeks and I am extemely happy thus far.
Driving back from San Diego, the first thing that I noticed was a wobbly rearview. After seeing this thread a day or two later, I figured that it would just be a problem that I would have to live with or attempt one of the fixes above.
I tore into it today and found only that the large nut in the base next to the spring loaded mounting lugs (through which all of the small wires go) was just ever so slightly loose. Tightened it up and all is well. None of the plastic parts or tabs appear to be broken.
Other than cracks in the plastic mounts for the visors, and cracks in the plastic cover around the rearview assy, I have yet to find a single thing broken or not functioning in this great car. Not too bad for 10 years old. Not to mention that it is a blast and pure pleasure to drive.

How did you "tear into it", dam?
I have a 96 SL500 with the same problem...except for MY model year, athough it does NOT have the electric motor running it...it DOES have the red ball (for the remote locking-unlocking gizmo) on it...and I would need to be VERY careful with it. Can you describe how it dis-assembles please?


I just got done replacing one of the bulbs in my third-brake light array on the trunk...what a nasty job THAT was! I'm STILL bleeding!

My '96 S320 had the same problem, same crazy price for new. After calling & emailing wrecking yards all over the country I turned to ebay next. It took 4-6 months but I ended up with one for $150 in good condition. I'm very careful with it and it has been good for over two years. I thought I would not be able to use the remote but that must just read the signal since it all worked with my old remote.

I just picked up a clean 1996 Sl500,, only a few issues,, yup one a little loose not that bad rear view mirror,, so thank you for the feedback,, and yes the 3rd brake light on Lid doesn't work... should I attempt or let sleeping dogs lie,lol I understand it could be a fuse which i saw is a designated fuse for just the third brake light
