2004 CLK320 Wiper stopped working
Just bought a 2004 CLK320 Convertible 2 months back. Car was perfect until the wiper stopped working suddenly. Initially, the wiper wipes once at position 1 when I activate the right turn indicator. Now it stopped totally. No wiping action regardless of position 1 to 3. Mist and washer fluid pump don't work too. However, turn indicator and high beam works though. I've changed the 40 amps fuse but to no effect. Should I try changing the relays? I hope I don't need to change the combination switch though. Appreciate your advise please. Thanks!

Rodney and Billy, Thanks for your advise.
Is there like a quick fix that I can try out first? I've read about spraying contact cleaner. The switch is so concealed. How can I access the internals to get the contact cleaner in?
As for the combination switch, any idea what is the part number and where can I get parts that are reasonably priced? Can this be a DIY job or I have to go to a Merc Specialist? I'm in Dallas, Texas. Any recommendation for workshop that specialises in Merc repair?
Apology for the number of questions. Still exploring with this car and trying to minimise any repair cost on this car. Thanks again for reading and replies.

Assuming you are int he USA (please update your forum profile!) then parts.com is a good place to order discounted OEM parts from the dealer network. As for it being a DIY, yes, you can if you think you can handle it:

I guess you fixed your problem by now. I've had the same . Problem was the interlock switch on the bonnet (hood) catch. I filled my washer bottle closed very thing up and hey presto no washers or wipers. Searched the internet and found a blog describing my problem. The guy went to a Merc dealership who just opened the bonnet and slamed it shut. Did the same to mine and the washers and wipers started working again. I think its an unwanted feature. Surly the bonnet open lamp should be on the same switch so at least the user has a clue whats wrong.

Rodney, Thanks for the advise I'll look to replace the switch and update everyone.
Also, my seat driver seats adjustments and steering column adjustment have not been working and after one day diagnostics they worked for couple mins as I moved the driver side control module. Then it stopped working, I tapped it and it worked again. I think that should be a clear sign of bad control module. And now its not working at all

quick update I just installed the faulty seat controller and it was clicking a lot. The wipers worked but the steering wheel adjustments didn't move. Everything is pointing towards faulty seat controller. I'm surprised that MB has seat controls, steering wheel adjustment control, and wipers controls in this single unit.

OK, here's how things work. Instead of running bundles of wires from every switch to every motor or light bulb in the car, it uses a CAN bus. It's like a computer network. Actually, it is a computer network. The buttons on the door panel are wired to the Door Controller which is a small computer that takes those inputs and sends them as signals across the CAN. The Seat Controller, which is a small computer under the seat, receives them and actuates the motors accordingly. On the steering column, all the buttons on the wheel and the stalks on the column, as well as the adjustment motors are connected to the Steering Column Controller. The Seat Controller stores the memory for the three positions. When you press the recall button, the seat controller moves the seat accordingly, and then sends signals to the Steering Column Module to instruct it to move accordingly.
There is some commonality here. The Steering Column Controller handles both the adjustment and wipe stalk signals, so it could be a problem. But it could also the be the Seat Controller or even the Door Controller sending bad signals. But neither of these have anything to do with the wipers, so if they are the problem, then the wiper stalk itself is likely that issue.

Rodney, I replaced the driver side control module and everything is working fine except I can't erase SRS airbag error B107C. I have C4 multipliexer with DAS software but it doesn't want to erase the airbag error B107C. Any ideas what I could be missing?

B107C is a failure to communicate with TeleAid. Since you have SDS, go through its diagnostic procedures. Just click on the actual error you get and it will give you some steps to investigate. Since your TeleAid system is the defunct analog type, you might as well disable it anyhow. I can't find the steps right now, but I think they are posted on the forums. I seem to recall you have to disable TeleAid, then turn off its error messages on the instrument cluster.

Try this once connected to the vehicle with SDS"
Navigate here:
Control Units -> Body -> Air Bag -> Control Unit Adaptations -> Read coding and change if
necessary
Change the "Emergency Call System Fitted?" setting to "NO" and then transfer coding. After that, reset the error in the airbag system. Also, I found this to remove any messages from the instrument cluster:

navigate through the following menus: Control Units --> Information and communication --> ICM - Instrument cluster with maintenance interval display --> Troubleshooting by means of complaints or symptoms --> Messages from the emergency call system are displayed in the instrument cluster
Change the coding from PRESENT to NOT PRESENT.
Once the coding is done, cycle the key to ensure that the message is disabled in the instrument cluster.

Rodney, I did install the new program without emergency call and now the SRS light is flashing.

Are there any codes stored? If not, you may just need to go through "Initial Startup". Check this thread:

Rondey, I updated the software to remove Teleaid and after going thru initial startup, everything works fine now. No SRS light anymore. The only thing I still have is instrument cluster for Teleaid. I believe I still need to update Cluster software to remove Teleaid connection.
