Replaced the driver's door handle on the C5 - £26 from Poland for a brand new one.
Stripping the door card and usual bits proved to be a lot less painful than anticipated, new handle just popped straight on, no messing (I did spend five minutes trying to find the screws holding the old one on - there were none it just hangs on with a couple of tags.
Replacing the door card not so simple to get it lined up right but managed without breaking anything.
Window and mirror controls took ages.
I've had them off a couple of times previously to clean as the contact pads get dirty and fail to work.
Interesting failures on reassembly, drivers window would go down but not up. On the second attempt it went up but not down.
The membrane with the carbon pads on is slightly out of shape and the moulded in pins don't fit the holes that keeps it aligned.
Third time luck though
Had expected an all day job but 90mins and done - as am I after being out in the sun for that long.
