It's been so long since I've seen my roof switch light on that I can't remember when it lights up.
Is it lit up when you start the car, turn the lights on, or only when you lower or raise the roof?
Thanks

I have older and newer in the household, and they light up when you turn on the parking lights, (both sides), or headlights.

Thanks Jesse,

I removed the switch today and tested the light. It works when I connect pins 2 & 3 to a 12volt source, so I don't think my switch is defective. I received my N10-3 replacement module yesterday, I don't want to install it until I complete a few tests.

Good idea.

Do you have to program the board with Star Machine?

UPDATE:

After doing some continuity testing and googling the crap out of SLK Roof problems, N10-3 failures, pin 58 info., I finally found the culprit. The module cooling fan apparently shorted out causing fuse #7 to blow via pin 58 at the N10-3 Module. When I unplugged the cooling fan from the N10-3 Module, the resistance on the non-hot side when from 2.8 ohms to 4.7 Mohms.
Installed the 5 amp fuse in #7, turned the ignition switch and the roof switch lit up for a second or two each time. Also, now the rear window defroster works.
Time to replace the Module cooling fan.

How's it going? Did you get a new fan yet?

(Hoping that's all that is wrong)....

Not yet, I removed the hydraulic cylinders for the vario roof operation and sent them to Top Hydraulics yesterday to be rebuilt. I want everything to work correctly before I sell the car. The fan is last on the list at the moment.

First the W201, now the R107? (Sorry if I got "R107" wrong).

Hmm...

No problem, R170, but who's counting. Yes, it's time to downsize. We only need one car, so eventually the SLK and Corvette have to go.

I've spoken with my family before about you selling off your W201, and consideration of selling the Corvette. I told my son you are fixing your R170 (I guess I'm getting dyslexic) to sell, and eventually the Corvette. He asked what will you keep. I said I remember you having a Hyundai Santa Fe. He immediately asked/pointed out that you'd keep that instead???

Well, please keep us updated. (Sorry I wasn't much help regarding the issue in this thread).

Yes, we purchased a new Hyundai Santa Fe Sport right before we sold the '93 190E. I always said I would never own a Hyundai/Kia etc. but after test driving several makes, we preferred the SFS. Only have 3,500 miles so far, so it will very low mileage when we trade it in. We haven't taken a road trip since the early '90's, only fly to destination and rent a car or cruise.
I'll be turning 70 this year so it's time to quit working on cars...the wife gets nervous when I'm under the Corvette. Bought it over 44 years ago, it will be hard to see her go.

Was it not SUV of the year, the Kia Telluride? We went to the LA Auto Show this year and test drove the fully loaded one they brought for the occasion. All I can say is WOW! I believe my son in one of the middle row seats had seat heater and ventilation/cooling switch to try!

I just saw somewhere online, to never work under a car alone! (Gulp! I don't know how many many times I've done that now).

70 is a big benchmark! Where are you going to celebrate??? My parents, whom we live with, are in their 80s now. My mother still goes to work 5 days a week. (I guess due to genetics that will be my future. I hope I love my job as much as she does)...

Definitely keep the 'Vette as long as you can. Good idea to get rid of the Mercedes first...

Congratulations again. I hope you have something fun planned....

Well, you could always sell it as is when you're finally ready. But I find it somewhat strange you mention this. We sold our home in Cleveland late last year and I got a good chunk of my down back, (house was sold at a loss). I may actually be able to bid on this one. Maybe I could leave it (extended) with you while I sort out a garage spot. I'm starting to spend on repairs of the W201 and stuff for my Scion iQ. (Gotta be careful I guess and restrain myself)...

I found a local place on eBay that sells used MB and Crossfire parts. I bought a used module cooling fan out of a 2006 Crossfire, exact same part as my SLK fan. I received it on Thurs. and installed it, now I have a module cooling fan that works.
Last Saturday I mailed 4 hydraulic roof cylinders to Top Hydraulics in Oregon to be rebuilt. The passenger side main and trunk cylinders were leaking. They are on the Fedex truck to be delivered to me today. Pretty quick turn around! After I get the parts installed and everything back together, the SLK should be good to go.

I'm impressed you're able to figure out exactly what's wrong without throwing parts at it....

Thanks Jesse, it's mostly my telephone switch experience that helps. Starting out in electro mechanical switches, then to electronic solid state. Trouble cards that were punched out paper cards, using a test pick to test for 48v and ground, then to diagnosing with laptops and computer stations. Relays and crossbar switches to circuit packs.
Troubleshooting was my world.

eBay is tough to find.

Have you tried www.car-part.com . Good for finding parts/salvage yards. Although lately seems like they are not updating inventory....

I've always had good luck with eBay, just put in the part # and I get lots of choices. The cooling fan was $24.50 with free shipping, only about 8 miles from my house but you can't beat free USPS Priority mail to the front door. Same with the N10-3 Module, $55 with free Priority shipping from South Florida to my front door.
Received my 4 hydraulic cylinders at 10:30 this morning.:D
