94 C280 wiper stopped working and no heated seats
 

I live in Maryland and we have a had a very dry year, so, as murphy's law states, as soon as we started getting some wet weather here my wiper stopped operating...I checked the fuse, it's fine and the washer still squirting kind of told me that already...It does nothing when I turn it on, it's not stuck as I have read in other threads...Is there any other type of a test I can run to see if its the motor or something else and if it is the motor, what is worse case scenario for replacement cost?...Thanx again in advance, I'm so happy to have found this forum, I hope I can give more help in the future than I need!

OH, and my heated seats are not working, came that way, anything I cna do to check those?

Sometimes the combination switch (the turn signal stalk with the windshield wiper switch on it) goes bad.

HOw can I check that?
