Wiper motor help

[leerdam23]

Hi

I have an SVA style test tomorrow for my T350 and the wiper motor keeps blowing the fuse. I have removed the motor and the fuse stays ok until the motor is connected again. So, does anyone have a pin connection diagram so I can find at least one wiping speed that will work?

No diagram but maybe the fault is in the stalk if the motor is OK?. Its off a mk1 Ford focus and costs about £6 from a scrapper/ebay. You want the one that does not have the rear wipe function on it

I have not had any trouble with the wiper switch. But several times I have had trouble with water getting in to the vertical spindle bearing bush on the motor gearbox and causing the bearing to become tight enough to blow the fuse.
Try removing the wiper crank arm and the clip on the shaft, and dribbling some thin oil in to the bearing bush, then running the motor. Repeat lubrication and running the motor.
You may need to temporarily re-connect the crank and assist it turning by hand when you switch the wiper on. If the spindle is tight you may be able to turn/move it slightly to assist oil entry to the bush. You may need to temporarily fit a slightly larger fuse, but do not leave it in place.
If the spindle is very tight in the bush and the motor does not turn at all, you may need to dismount the motor and open up the gearbox to ease things off.
Reduce water entry in future by putting a bead of mastic between the heads of the bolts for securing the motor to the plate.
