Wipers won't shut off

[Red-Eye]

Originally I had to manually park the wipers, but now I can't get them to shut off.

Thinking it might be related to the infamous "slow wipers" problem, I pulled everything off the car and cleaned & re-lubed the arms to where they are working nicely.

I didn't pull the motor apart, just cleaned the exterior up. Plugged the motor back in, and still won't shut off. Could it be the switch on the steering column? If so, any tips on what to look for?

Thanks...Robert

Which car?

The 71 does have a mid-cycle park feature which has a couple of wires attached to the back of the wiper motor crank-case. If one of those wires is disconnected or not making proper connection due to a break etc. it will keep cycling as it never gets to the "park" position.

The 74 has an intermittent wipe feature, as such it could be the intermittent relay that is either shorted or ....?

I'll leave the 83 to Stephen Blake.

The 1600's were very similar to the 71.

No worries, but did the answer I mentioned help you?

I guess I don't know what you mean by crank-case.

Ok, here goes. Hopefully my pic editing worked.

Wow, thanks alot...Robert

Well, the wires seem OK, at least from visual inspection. I loosened the screws and moved the Park Position Switch around some, but the wipers still wouldn't shut off. I'm wondering if the metal tang on the inside of the Park Switch isn't making contact???

Do a continuity check to ensure that the wires aren't broken someplace along their length.

As far as the park switch, that "bump" is supposed to lift the reed and break the circuit. Is the nylon pad worn out?

After this, the only thing I can imagine that may cause the problem is a down-right short circuit in the switch itself.

See the following pic.

Hope it helps.
