ws721 Posted January 9 Share Posted January 9 Is there an electric wiper motor set up for an 89 DM? Is it the same motor as a R? Quote Remember if it's got a hood it's no good!

Trico's area bit harder as they have shaped seals. Haven't done one of them, or needed to (yet).

mowerman Posted January 10 Share Posted January 10 My switch leaks, but I heard they’re also easy to rebuild. I’ve got lots of other stuff I have to do first. I haven’t even looked at it, but it pisses out of their pretty good. I was also thinking the same thing air operator. There is probably very little in there to go sour….

There is probably very little in there to go sour…. Bob IIRC it is the Trico's that have air to the motor when in the off position (for the self park feature) and so have air through the control at all times. Sprague (sp?) don't "self park" and shut off the air when turned off and you have to manually crank the knob counter-clockwise past off to park. Both controls are still available last time I looked. Both motors use "back pressure" on the exhaust side to keep them from being "floppy". Too often someone tries to get more life out of a motor by opening up the exhaust restriction, and they you end up with fast-floppy wiper movement. As long as the shaft splines are good, and the case isn't damaged, there is little other than O rings and seals to go wrong with them. They can take being frozen to the windshield with the motor "on" without damage, that could kill and electric.
