Wipers acting up

My wipers have been acting up lately. When I've been using my wipers for a while, they will stop when they are vertical, usually for about 5-10 seconds, then start again. There is no pattern to it, the amount of time they stop is random, and the frequency of the wipers stopping like this varies. Does it sound like my wiper motor is starting to fail?

My truck does not have intermittent wipers.

Thanks.

It's the switch. Real easy fix. Napa should have the part in stock. Hardest part is getting the light switch knob off. There is a trick to that.

There is a switch inside the wiper motor that runs the motor until the wipers are parked when you shut them off. It sounds to me like that's what's broke.

Cooltc, by just changing the switch from the normal (Off-Low-Hi) over to the delay does not give you that capabilities. There is a "brain box" that installs between the switch and the regular wiring harness as well. The nice thing about the brain box, is that the early 80's used the same box, if you need one, check out your local junk yard.

Its hard to diagnose since its pretty random. Is there a rebuild kit for the wiper motor or is it better to replace it with a refurbished unit?

Ziggy:
The switch I have does have a box in the middle of the wiring between the switch and plug, its not JUST the switch. I'll try and get a picture of what I have and maybe you can tell me if I have what I need.

It is hard to diagnose. I live in Oregon. It rains a little bit here now and then, so I always replace a bad wiper motor with a new one and go on about my business.
If you have the delay box and switch, it might be a good idea to install them first and check to be sure the motor is faulty.

If the box has a red connector on the one side (I believe the side that goes to the wiring harness) then you're in the ball park. Just make sure you ground the switch with attached pig tail when you install it.
