WTB - windshield wiper relay - round

Recommended Posts

If you can't find an original, this one sold by Jegs will work,  It is the same type of relay, works perfectly, and is inexpensive.

You can also adapt the cannister from your old relay to it, if you want it to look like the original.

And...your problem most likely isn't that relay.  All it does is turn the wipers off after you activate the wash-wipe stalk. 

 

If your wipers won't turn off after you turn them on with the wiper switch, the problem is with the self-parking mechanism inside the wiper motor.  If that's the case, PM me and I'll send you a column on troubleshooting that little problem.

So my problem is two fold - 1. they won’t turn off once turned on 2. High speed is so fast it looks like they are about to create vertical lift - one theory was bad relay (hence the ad) another is that the NOS wiper motor is for a 6v car and I’m running it in a 12v setup ?

 So I did some searching on the faq about 6v to 12v swaps and someone did mention that the 6v wiper motor would work but much faster - so seems like I  have a few data points to suggest that indeed that wiper motor is for a 6v set up not a 12v .

Not sure if that’s why it won’t shut off or if that is a separate (possibly related ) issue

I’d like to see that column. I think I’m having the same problem.

I’m looking for an early windshield wiper relay the round kind that typically sits against the firewall near the distributor.

 

That relay doesn't control the wipers persay, it is a delay relay that runs the wipers and windshield washer pump when the turn signal stalk is pulled back towards the driver.  This grounds the relay and the wipers and pump will run until you let go of the turn signal stalk, then the wipers will continue to run until the delay relay breaks its connection as the bimetal switch cools.  Some people have used a delay switch for 1970 Dodges that controls the courtesy light when you open the door.  I did a blog entry for trouble shooting the wiper/washer system you also might find helpful.
