Hi-

My wipers on my 1990 245 stopped working recently. The fuse looks good, the switch on the wheel stem works for the fluid squirter but not the wipers (I assume that means the switch is ok?), and I have cleaned the motor's ground strap connections and also installed another ground wire just in case.

I would like to see if the motor itself is the problem. I saw in a previous post that someone hooked their wiper motor directly to the battery to check it. How would I do this? Attach wires to the battery leads and randomly poke at the pin connector terminals until it starts working?

Thanks for your help. I have done a few more complicated (for me) repairs like the timing belt and water pump, but this is my first foray into the electrical side of things. It's a little daunting, but I need those wipers (believe it or not it's actually raining here in southern CA!)

Again, thanks for any help you can provide.

1990 240 Wagon "White Lightning"

This past summer my 240 wipers started to barely move. I disconnect the linkage at the motor and the problem was with the motor, it sounded terrible. Obtained a new motor which came with its gearbox. I tested that unit before installing and it didn't move at all. The unit was the rebuilt kind and painted. In the business it's called "spay and pray", a term first used by steering rack rebuilders. I got my refund and took mine apart and found the field magnets had let go of the motor housing. JB weld and a tight grip while drying fixed the problem. Fixing the small water leak on that rubber body grommet took longer. Have fun, Keith

I would use a VOM to check for voltage at the motor. If not present, you know where the problem lies (switch, wiring), if present, you know which wire has 12 v on it.
