wiper motors

[ocean]

I have 3 windshield wiper moter that need repairs or replacement. They are off my 1985 Ocean Alexander aft cabin trawler, the only markings on them are TNK 85910-3400,80-12v
3928.
Any help in identifying the Mfg or a repair source is appreciated

Further to my earlier post I am attaching 2 photos that might help to Identify the wipers

It doesn't look familiar. If they don't work at all, 1st have you checked to power and ground leads to rule that out. And next , I'd definitely open one up and see if it's fixable.

If you take off the mounting bracket maybe there will be better ID on the motor case? If necessary you ..might... be able to attach a new different brand motor to that bracket to avoid new windshield holes . Make sure the shaft diameter length are comparable, taking into account the mount.

Sandy thanks for your imput. Yes there is power to them,they try hard to work sometimes 2 or 3 strokes. I believe they are partially or fully seized I will take them apart as suggested and try some light oil

I've never been afraid to take any Wiper motor apart and see why it wont run.
I've almost 100% effective in cleaning etc and making them work agains. Horns too.
Almost anything can develop corrosion inside in a Salt water environment.
If the parts are not destroyed, cleaning and reestablishing the connections does the trick.

Shoot the shafts and bearings with PB Blaster. Wait a day or so, then power up. Please report back on outcome.
