Okay dokey, tonight when I got back to base, I noticed the LH headlamp wiper had 'parked' sitting near vertical
. The only way I could get it to park at the bottom of the headlight was to keep switching the ignition on for a couple of seconds.
I've had a look through the Haynes manual and I get the general drift about getting to and removing the headlamp wiper motor. That seems to be the easy bit.
I've had a search through the forums and found a lot of people have had headlight wipers with the same symptoms as mine, albeit on 850s and V70s. A common fault seems to be dirty motor commutators. There are some really good detailed notes about disassembly, cleaning and rebuilding.
Think I'll get the motor out, re-assemble the front of the car so that it's driveable again and do the wiper motor job on a work bench in my own time.
Has anybody else had a stab at doing this job on a V40 - is it possible to open the casing and dis-assemble the motor then rebuild it so that it works properly again?
