I'd suggest to disconnect the linkage from motor to the wipers and try to identify the faulty part. Blowing fuse basically means that the wiper motor draws too much current.
So when disconnected, move the wipers by hand to see if they are meachanically ok. Then operate the wiper motor, see, listen & feel if it makes noises, gets hot. If so you may try to open it, clean and lube it. Or replace ...

 

The linkage is a bit squeaky. I took it and the attached motor out and greased the linkage really well. Turned on the wipers to test it and get the grease moving. I worked for about 10 seconds then blew the fuse. Put in another fuse and it blew immediately, the motor didn't even turn.

Put my multimeter into ohm mode and tested the motor. Acording to directions I found on Yahoo Answers, I should get nothing but 0.00 when I touch one lead to the positive on the motor, and the other lead to the motor housing. Anything above 0.00 is bad. I wasn't sure which wire was which, and my Haynes manual had the wire colors completely wrong, so I tested them all. They all gave a reading above 0.00.

So I guess I just need to get a new motor.

 

Check the ohms of both leads to see if it is really a low number.


For whatever size fuse this is the formula for the amperage based on ohms. Voltage will be 14 or so.

[SIZE=-1] I = V / R (Current = Voltage Divided by Resistance)

Not sure what you mean. Are you talking about testing the power coming from the connector, or the connector on the motor?

Or testing the multimeter by touching the leads together? I do that and get around 0.22.

Should I have scrubbed the motor housing a bit to get rid of any corrosion?

 

Just the wires from the motor.

 

Not sure what you meant by "Check the ohms of both leads". The motor has five wires/pins. I set the multimeter to 200Ω and tested each pin with each other. Highest reading I got was 1.28.

I ordered a remanufactured motor from RockAuto. Hopefully that's all I need.

 

Good news is that I got the new motor and it runs without blowing the fuse, so that problem is solved.

Bad news is that I forgot to mark the position of the motor shaft in relation to the linkage. Now I can't figure out how to get them back in proper alignment.
