Lotus Excel

One of my windows packed up today,went down refused to go up ! could it be just the switch ?it was operating very sluggish anyway.Any ideas ? were do the switches and motors originate from or are they just lotus ? cheers Dan.

when mine did that it was because the channel the glass sits in had corroded which I was told had broken the circuit and so stopped working. New channel cost less than a fiver and it is "fine" now

Thanks I hope this is the case with mine

Silicon spray can be useful to keep them running smoothly, spray into channels

could be the motor which is a gm delco unit mike at lotusbits does them for 30 quid second hand.
