Last week my front right window stopped going up. It would come down but wouldnt go up on the switch.
It went up if I used the Infra red convenience closing on the remote.
Luckily I still have the 500E donor car hanging around... Took the convenience module from that. All was ok for a couple of days.
Then today i rolled down the drivers window and the passenger went down all by itself!
Would not go up either on switch or using convenience.
So I have ordered a third used module from ebay.
Are these problematic or am I just unlucky?
I tried another window switch incase that was causing some issue but still the same.
I had to put the original module back in so that I could close the window using convenience.
I took the lid off both modules.. both look perfect inside.
