Hi, have a 1997 merc and the wiper only works at one speed and does not return to its seat when i turn off the wiper ? i was told it could be the relay or the combination switch but both are costly items any suggestions on how to identify the problem and eliminate one or the other ?
my other problem is with the air blower it works ok but does not work for the windscreen, when in the windscreen position, but no air coming out for the screen ? any ideas ont this also please, thanks again
