Hi, Sounds like you have a leak in your heater matrix. Is the engine loosing coolant ?
Chris.

Are you certain that the A/C compressor is engaging?  It should be on when the defroster is on.

My 1991 300sl has a new problem, now that it has gotten cooler.  When it is cold the windshield fogs up, I put it on defrost does not get any better on drivers side (it is putting out warm-hot air on both sides on windshield.)  I have tried have just warm air only coming out on windshield & then tried on windshield-floor button.   Fog up so bad hard to see & keep it wiped so I can see.

 

After some time it will clear up & then its fine.....problem occurs on start up.

 

Lately, I have tried not to have any heat coming out, that seems to keep windshield from fogging but is bit chilly. 

 

any suggestions?

I've used these myself and they're perfect:  http://www.astro-nut.com/mb-d oor.htmlCan't give you much advice about the mechanism without first getting the door panel off and taking a look.  You'll probably find a problem with either the motor or regulator.  I had similar trouble with my '95 where I first started getting a loud metallic "clank" sound when the driver-side window reached the full-down position.  The problem continued to get worse until the window jammed about halfway down and wouldn't move in either direction.After pulling the door panel, the problem turned out to be the window motor itself, which mounts to the inside of the door frame with three bolts (the regulator is actually riveted to the door frame).  The OEM Bosch motor had a black molded plastic body - the bolts pass through the holes in the door frame, then through some metal standoffs/spacers about ?" long, and finally into plastic 'posts' in the motor body.  An incredibly stupid design, because there's huge torque on those three motor mounts as the tiny motor gear drives the window regulator up and down.  Eventually, the plastic posts into which the mounting bolts fit cracked into pieces (I found several at the bottom of the door cavity), and this lets the motor flex or even move when torque is applied.  The 'clank' sound turned out to be the motor gear jumping its teeth against the regulator, which also destroyed the gear teeth over time.  Only fix was to replace the whole motor assembly.If you do find yours broken this way, shop around:  I located a used motor on eBay from a 1992 SL at about half the cost, but more importantly, it turned out to be made by a different OEM in the earlier cars and had a nice cast metal body instead of the cheap plastic used on the newer cars (plastic is also used on new replacement motors).  The metal body also didn't require the use of spacers, so the whole assembly is much stronger and more stable.  While I had everything apart, I also re-greased the regulator gear and the vertical tracks until I could manually pull the glass up and down smoothly and with little effort.  It works like new, and no more problems since then.Hope this helps!     Rob Vonderhaar     Leesburg, VAPS - If you haven't done it yet, you might want to think about replacing the door strap at the same time.  It's a $25 part that frequently breaks on the older cars, and takes only minutes to replace while you've got the door torn apart.  Otherwise, you'll have the fun of ripping it all apart again later like I did...  :)From: r129list-bounces at mbcoupes.com< /A> [mailto:r129list-bounces at mbcoupes.com] On Behalf Of gerhard stefandlSent: Saturday, December 13, 2008 4:06 PMTo: r129list at mbcoupes.comSubject: [R129 SL] r129 sticky windowI have a '94  sl500 and suddenly the window jams when I lower it.

Though clean and with agood history it required some catch-up maintenance.  After running the MBService info gauntlet we now have enough information (factory authorized CD,Service introduction manual for the 1990 SL series - thanksBooksForCars.com) to address most normal service issues.  What I've notfound is information about modifications and parts to boost the performanceand reliability.  What standard formulas would a professional MB specialtyshop employ that a handy enthusiast might be able to do on their own?  Arethere articles available where these Pros share their knowledge?  Living inCentral Washington offers plenty of great roads for driving the SL but notmany (any) independent MB shops or clubs.

Options are build a 6Lvarient w/ stand alone fuel/spark..  Or, engineer a rear mount turbosetup..  I beleive Kleemann or someone similar had or was working oncentrifugal blower for the SL's, but cost was around 25K or there about.In short there is No easy/inexpensive means by which one can make these carsfaster.  You already have the 'hottest' SL by owning a 92.Only other option that would net a few HP would be a custom exhaust from themanifolds back, but expect that to run around 2K if done correctly.If a 6L is of interest we can provide you with said motor and stand alonefuel/spark management.Jonathan-- Blue Ridge Mercedes/AMG EastOffering Enthusiast Service, Restoration and Tuning.Providing quality parts to discriminating customers in all parts of theworld.Located in the Greater Atlanta area.http://www.blueridgemb.com404 805 13571996 S600 Euro1991 560SEC  Euro ECE1991 560SEC GT28 Conversion1989 190E 2.6 factory 5sp1989 560SEC ECE AMG Japan1989 560SEC AMG Solid Lifter/6800rpm1988 300TE1987 300E AMG1986 560SEL AMG 6.0L 32V1986 AMG Hammer 6.0L 32V2006 Z4 3.0Si M spec 6sp-------------- next part --------------An HTML attachment was scrubbed...URL: <http://www.pairlist.net/pipermail/r129list/attach ments/20081214/1a2578ed/attachment-0001.html>End of R129LIST Digest, Vol 47, Issue 3***************************************
