GLS Windshield Wipers Not Working

I'm experiencing a frustrating issue with my 2016 Mercedes GLS with a gasoline engine. The windshield wipers have completely stopped working. They don't respond at all when I use the wiper switch. I scanned the car and found an error code related to the wiper system stored in the error memory. Based on some research, the likely cause is a defective cable or plug connection within the system. I've checked the fuses, and they seem to be fine. Before I start tearing apart the steering column and digging into the wiring harness, I wanted to see if anyone else has encountered this problem. I am aware that I need to check the wiper motor and the turn signal stalk as well. Any advice or insights would be greatly appreciated. I am expecting a repair cost of about 95€, does this sound right?

I am writing with information regarding your reported issue with the windshield wipers on your Mercedes GLS. I had a similar problem with my GLS, although I did not check the error memory. The symptoms you describe align with my experience. In my case, the issue stemmed from a corroded connector within the wiring harness that leads to the wiper motor. Could you describe the specific error code you are observing? This information may help narrow down the potential causes.

Thanks for the quick response. The error code is related to a communication fault within the wiper system. I'm not sure of the exact code offhand, but it indicated a break in the circuit or a faulty connection. Where exactly was the corroded connector located in your vehicle? Was it near the wiper motor itself, or closer to the steering column where the wiper switch is located? Also, did you perform the repair yourself, or did you take it to a mechanic?

In response, the corroded connector was situated near the wiper motor, beneath the access panel. Given the error code pertaining to a communication fault, it would be judicious to inspect the integrity of the wiring harness and the connections therein. I must emphasize that working with electrical components requires a meticulous approach and a comprehensive understanding of automotive electrical systems. I would suggest consulting a qualified technician to mitigate the risk of inadvertent damage. While a repair cost of 95€ might seem reasonable, it is contingent upon the specific fault and the labor involved. I took your advice and focused on the wiring harness near the wiper motor. Turns out, you were spot on! I found a corroded connector, cleaned it up, and now the wipers are working perfectly. Thanks for pointing me in the right direction! Saved me a ton of time and potentially money. I really appreciate the help.
