Windshield Washer Heater Problem on CLK

My 2008 Mercedes CLK gasoline engine has a windshield washer heater fault at 191116 km. An error is stored, and the spray nozzles freeze in cold temperatures, making the washer fluid system unusable. Diagnostics suggest a defective cable or plug connection. The repair should be about 95€. Has anyone else had this issue, and how did you fix it?

Washer fluid problems are the worst, especially in winter. I had a similar issue with my old Volvo where the washer motor would make noise, but nothing would come out. Clogged nozzles, frozen lines, the works. Did you check the washer motor itself? Maybe it's not getting power, or maybe it's weak from trying to push through ice. Could that be contributing to your washer heater error?

Are you suggesting that a partially functioning motor could overload the washer heater circuit, triggering the error code and contributing to the frozen nozzles? Or is this a separate issue?

Yeah, that's what I was thinking. Maybe the motor's struggling, drawing too much power, and messing with the washer heater. Honestly, troubleshooting electrical issues can be a pain. If you've checked the fuses and connections, it might be worth taking it to a workshop. They've got the diagnostic tools to pinpoint the exact problem.

I have inspected the fuses and connections, but further diagnosis requires specialized equipment. Considering the potential complexity and the repair estimate, I will visit a workshop. Thanks for confirming my suspicions and providing additional points to consider.
