Intensive Washer Motor Seized
1990 S4 RHD
I find my intensive washer system is very handy.
It stopped working recently and investigation shows that motor is seized.
Does anyone know how to get the motor apart to repair?
Thanks,
Myles

I've r & r'd a few of them. They come apart pretty easily. Where the gear is seized inside, due to corrosive build up, I carefully take it all apart using liberal amounts of WD-40 to loosen things up, and my dental pic set to gently pry things apart. The last gear is tough, but gently push the metal retaining pin out from the outside to pop that gear. Then use a tiny drill bit, matched to the hole size, and by hand put it in and twist it around some. Clean out all of the cavities inside the plastic housing, gently scrape off any scale build up, put the primary gear back in, then the other gear, put eveerything else back together and button it up. It will work like new.

I think I paid $14 for a new one from Roger. Pretty surprisingly inexpensive, especially considering they're made in Switzerland. I was also kind of surprised that the pump cost significantly less than a bottle of the washer fluid it's meant to deliver.

Thanks all.
I tried to find out a price from 928 Int & 928 Spec but couldn't find it on their websites. Also freight is likely to be several times the part cost (at the prices above).
Reversing polarity was the first thing I tried but it wouldn't budge.
I got it apart and cleaned it up basically using the method that Ed described.
Wally - I did lubricate the motor bushings.
I will probably order another one with my next round of parts (TB in a couple of years I hope).
Thanks again,
Myles

Throw the useless piece of crap away. I have tried to rebuild about a half a dozen. They never last. I have a box of used ones if any one wants them.
I purchased a plastic pump from Rock Auto for about $11. It fits right in the same place and will work long after the porsche replacement is dead. There are things and times to up grade the car. This is one of them. Good luck.
Oh I went to the electronics store and picked up a pig tail to attach to the pump. The pig tail fits the plug on the Porsche side. A tie strip and you are done.
