Hi All,
Today I took out my 2004 Mercedes Benz E320 (89K) 4Matic for it's annual
NYS inspection. The car spends most of the time in the garage with very
limited use. I went to turn on the window wipers and they did not work in any
of the positions. The wipers do work when I pushed in the arm to activate the
wiper fluid for a cleaning. I don't remember the last time I checked the
wipers.
I checked the fuses even though the wiper motor did work in the wash position so there is
power. Research pointed to a faulty "combination switch". That repair is a bit involved
so I am reaching out for any other suggestions before undertaking removing the steering wheel, air
bag etc to replace the "combination switch".
Thanks in advance!

Isn't there a procedure relating to turn signals that don't work where
one pushes in the hazard lights switch 100 times to fix it? Would it
help to just work the wiper switch a whole lot of times in an effort to
wear off any oxidation on the switch contacts since this is a car that
sits a lot?
