'79 300D Driver's side window.
Four months ago had new window motor
installed. O.K. Now the switch operates the
window intermittantly. When pressed either way it will not respond (the dome light does NOT dim, as a test indicator).
When released and pressed again a couple of times it will work the window.
Since the dome light doesn't dim does this point to a faulty switch rather than
say, a sticking window rail ?
Thank you for your tips and opinions.
