The Blue car makes a horrible noise in the drivers door when locking and the windows sort of go down and sometimes up of a fashion....door trim off !
I'm guessing that the actuator doesn't look like this!
A quick search threw up John's post with part numbers here:
viewtopic.php?f=35&t=19607&p=287362&hilit=actuator#p287362
First of all where is/should the actuator be? And any advice on removing it and testing the circuit?
