sunroof control switch
1998 E320 wagon
Just to refresh, to resync either express feature of windows or to resync the sunroof open them all the way and then close them and hold the switch for 4 seconds before releasing. If you are new to the model, note that the sunroof only opens half way on the first push. That is by design.
Frequent loss of 'sync' is often a symptom of a failing battery.
The switch is A210 820 34 10 and is about a $50 part at the dealer.
I posted another thread about windshield washer nozzle adjusting. What's the right way to do that? Can you help?
Thanks, Mike
I think once they're off you can see access to the switch. I haven't seen a DIY but probably worth checking.First I'd check to see if the holes in the spray heads are obstructed with dirt or salts from tap water. Sometimes a small sewing needle can be used to clean them. Don't use something so big that it enlarges the hole or you may lose pressure and get a weak spray pattern. I don't know if they can be adjusted as far as aiming them.
These cars have various electronics which can cause an error. The system will reset itself but if the problem is still present the error message will return.
