Wipers come on randomly, with the stalk in the off position. They come on and go off by themselves. The different speeds positions and squirters work when moving stalk. However in the off position they sometimes come on, staying on for several minutes at a time. When they do shot off its always in the home position.
The three main components seem to be the stalk switch--->relay--->wiper motor. (is it safe to say that if the relay was broken the wipers would not ever move?)(Symptom is not dependent on speed)
Looking for suggestions to isolate/check these components.
Thankfully it has not rained in CT for like 2 weeks. Anyway I finally received a used relay from EBAY. $20 bucks. I popped it in and now the wipers rest in the up position...F-c- me!! Sorry about that.
2 steps forward 1 back....I guess am going to search if the arms/motor have to be set in a certain position. a zero degree point or something...
Thank you folks for your suggested sequence of replacement...I think the switch can safely be ruled out now.
Relay was the problem...thank you again folks for recommending replacing the relay first. After checking with Bently I was able to see sequence of setting wiper motor to park position and reattach arm in correct orientation. After a couple tries I got it right. Wipers works!!!on to the next repair.......Which is replacing the Electronic Throttle Actuator on my wife's W124 E320 Wagon...Over to the Benzforum.
Thank you again everyone for your time and suggestions...truly appreciated!!!
