Many people leave then in a non working state but they are not difficult to repair. The case closure is held shut by 12 clips. (9 short & 3 long) The important thing is not to break too many of them. This can be achieved by heating the motor overnight on a domestic heating radiator.


Ease out each clip it turn 'til the base jumps free.





Next, tap out the shaft.





Test the motor at this stage, the problem could be just a sticking shaft. If the wiper was in the parked position when you took it off Make a note of the position of the line on gear D this will help when reassembling. Otherwise it's a case of trial and error to get it to park in the right place. Remove plate 'A'



and the gears from below it as pic 5.



Test the motor by connecting the black -ve lead the the black terminal in the plug and the +ve wire to point B (pic 5) if the motor turns slowly or turns then stops there could be lack of residual magnetism in the motor. Touch the red wire to point C of 10 secs or so then back to point B. It should now turn normally. Reassembly is the reverse of the above. Grease as necessary. Make sure that the 'dust cap' is back in place on the shaft. I did two in around three hours this afternoon.




(At least half an hour was spent finding the correct parking place for the offside motor) Early motors are slightly different they have a straight rack rather than the short curved one.

Sorry about the edits... I got the pics in the wrong order.


Make sure the the +ve and -ve leads are correctly connected making the motor run backwards will bend the parking terminal,

Clever you, well done, looks far too complicated for an idiot like me. Assuming that the 93 models are similar do you do a free removal/repair/reassembly service to North Wilts by any chance? I can offer you a cup of tea and am willing to bore you to tears while you see to my Saab. The round trip would be only 400 miles or so.

Nice one, be useful when my spares run out as the moment if one packs up (which one has) I've just swapped it over for another!

Nice piece of work.........could keep me busy for a few winter nights

Nice job. When did you last need them though? Removed them from the vert. Cleans the lines up nicely. I have a big bag of them from various cars.

I'm one of those people who like things to work as they should. Having said that they have been removed from the Ruby to fit an FMIC.

It's surprising how much room removal allows for an inter cooler or simply clean cool air flow. Never mind the weight from in front of the axle line. Once in thirty years have I needed to stop and clean my head lamps.

Well done! I also hate having things not working and I do find them useful - it gets rather mucky around here in winter and having these working avoids having to stop twice a day to clean the headlamps.

When I did the 9000 motors here, I did some research and found that there is a reliable way to ensure the parking mechanism is aligned. I think I found that on a Volvo forum. As long as you get it near enough, then the mechanism will sort itself out the first time it is run.

These motors are used on Volvo, Mercedes, Saab 900/9000 (and 9-3, I think, as well as 9-5) and other cars. I think the same thing is used on the 99 Turbo but I'm not sure on that. As far as I know, only the mounting hardware, spindle length and sweep angle vary between models, as well as LH and RH variants. As you say, it seems that earlier motors were slightly different internally from later ones.

I'd done an earlier one ('84 900 GLi) many years ago. So I knew it wasn't a difficult job. The main difference (as far as I can remember) is the rack that runs from gear "D" is straight whereas the later one is curved. Presumably this gives a more constant wiper speed. The other difference is the parking switch terminals appear to be a lot stronger those in the earlier motor. The older ones were very flimsy and bent very easily. (Guess how I know )

good post I have one stuck wiper on my 9-5 looks daft when only one works
