V70 Headlight Wiper Motor

Hi,

I have a V70 Auto 1999 SE and the drivers side headlamp wiper arm is in an upright position...occasionally it moves so obviously either the motor is going, has gone, or is just playing up intermittently. I dont really have the time to do repairs myself and when I do, I usually end up with a worse problem (usually just after the stores have closed).

Does anyone know if it is a long and...therefore expensive job...for a garage to take the wiper motor out and replace?

I noticed there is a step by step for a C70 wiper motor replacement on the forum but not for a V70. Be grateful for any advice.

Driver's side is I believe a bigger job than nearside - I had nearside replaced recently by my dealer and it cost c£200 inc. VAT for the motor and fitting.

clearly martin the call is yours, £200 from main dealer or you could source one off ebay for £15

and allocate half a day to fix it if you are not mechanically swayed...i know which way i would go but if you dont fancy it, looks like you will have to bite the bullett......
as a point of interest (or not) when my 850 one went the wiper only moved when i turned the ignition on and off and then slowly, i turned the ignition on and off till the wiper returned to the parked position and i then disconnected it...for some reason having a wiper permanantly in the upright position, or just not right really bugged me....
cheers

HI,
I've just bought a 1998 V70 and that's exactly what my driver's side wiper motor is doing (why the driver's side where you need to remove lumps of other stuff to get at the motor?).
I just removed the blade for now...
I'm wondering whether there's a 'self-parking' switch inside which isn't open-circuiting properly, so it keeps nudging the wiper blade a little more. That being said, could it be an electrical fault within the motor body that's not enabling it to work properly, and not a matter of the gears being stripped (which I gather is what can cause this motor to fail)?
If you find an answer, do please post it! And if I do, I will.

The reason the motor will slowly return the blade to park on repeated switching of the ignition is that there is, within the motor assy. an electrical thermal overload cutout switch. When the motor or mechanism gets tired the motor draws more current and the overload switch operates. Switching the power off allows the switch to cool and reset.

I need to investigate my driver side motor again because it too stopped working, but seemed fine after I dismantled and cleaned everything. Now I've disconnected it as it's a pain to have the blade sticking straight up! I wonder if the thermal switch doesn't get weak with age and cut out at a lower current as the motor works fine with the wiper blade away from the headlight glass. Next time I may just disconnect the thermal switch.

Does anyone know what the normal current draw should be for these wiper motors (not the fuse rating as the thermal cutout should operate before the fuse blows)?

I found that you need to dismantle the actual motor and clean the commutater for the fix to be effective.
Make a note of how relative positions of the gears etc. as there are lots of ways of reassembling the thing incorrectly.
From memory the motor took about 3 amps free running before cleaning and about 1 amp afterwards.
