New Wiper Motor, No Power

I just replaced my wiper motor because the old one wouldn't stop in the down position. I simply put in a new motor, and plugged it in exactly the way it was before. Now I am getting no power to the wiper motor at all, and the fuse blows everytime I turn on the switch. Any ideas?

Re: New Wiper Motor, No Power

You obviously have a short somewhere along the line. Is the motor a good quality rebuild?.....I've seen some bad rebuilds out there. If the motor is okay, then the problem is most likely the switch. Trace the wiring up to the switch. Look for any exposed wiring and wrap it in electrical tape if necessary. Also, are you using the correct rated fuse? It should be rated at 20-25 amps, depending on the year of the car. Just make sure never to use a higher amp fuse than is called for.

12 volts is applied to the motor any time the key is on. The switch is the ground for the circuit. Unplug the wiring from the motor and replace the fuse. If the fuse blows, the short is in the wiring, if the fuse blows when you connect the motor, the problem is in the motor. jack

Re: New Wiper Motor, No Power

The motor is from NPD, so I would assume it is a quality rebuild, but I swear that half of this catalog stuff is hit or miss. I will try your suggestions tonight and see if I can trace it back. I'm using 20 amp fuses. I believe this is correct for a '68. I have to buy more today, since I fried 4 or 5 of them last night. Thanks for all of the help, and I'll keep you posted.

Whenever I replace electrical parts I like to bench test first,hook up to battery or battery charger on bench.Eliminates a lot of headache sometimes.
