wiper issue, could it be the switch?

I am having the a problem with my wipers. I changed the motor three time and it does the same thing. The post will rotate around but the post does not spin, it only make a clicking sound. in turn, my wipers only move up and down about 3 inches. My wiper switch has a lo and hi setting but it does not work in low and sorta works on high. Could this be an electrical problem with the switch. Any suggestions?

Sounds like you have a bad switch or a bad ground...

Sounds to me like a bad ground AT the switch. Need the year of the car to help.

Re: wiper issue, could it be the switch?

This is an 86 Camaro. The switch has no delay only lo and hi. When I move into lo it doesn't work. When I move it to hi the motor will rotate the post but it doesn't spin the post. Because it doesn't spin it does not lift the pivot arm. The pump squirts fluid but does not activate the blades at all. My next trouble shooting step is to replace the lever switch on the column. My current switch only has lo and hi, no delay. Can I put a switch that has a delay or is there another component that ii will have to replace? Thanks for your help.

The motor has to have a delay board in it. It would be located under the plastic cover and have a flat two prong connector sticking thru the cover. To isolate problem between motor and switch, make a test lead the looks like an "h". put two wires in one foot (of the "h") and crimp on a flat spade terminal. Put an alligator clip on one end of the wire and another spade on the other wire. Connect the spade terminal to the outside positions of the three terminal connector of the motor. (remove the three terminal factory connector) Ground the lead with the alligator clip. Apply 12 volts to the center terminal. If memory serves me , with both ends grounded it should park the motor. With just one spade terminal on the end connector one end is high and one is low. This is the bench test of a round wiper motor, it only works this way on motors without delay. If motor operates correctly this way the problem is with the car's wiring or switch.

I hope that's not too confusing.

Re: wiper issue, could it be the switch?

Thanks Jeff,
Is this the board you are refering to? If so, I am only seeing 1 prong. Do I need to get a new board for this? I'm having a hard time finding a lever switch that has no delay. Or is there a diferent way to test this one?

That first link is different than I've ever seen. I think the motor in the second pic should test the same.

Do you think this circuit board is for non-delay switches?

The wiper motors I've worked with only have board with delay, Not sure what that board is about.

Had a similar problem on my 68.
I had a dud wiper motor and replaced that, then I dicovered I also had an intermitent switch (internal parts worn causing poor contact)
It is very important that you have a good earth to the switch of a 68.

I think the best thing I did was bench test the switch and wiper motor before installing to make sure everything worked.
It saves the frustation of fitting everything, finding out there is a probelm and then having to pull it all out again.

Re: wiper issue, could it be the switch?

I got them to work. for some reason, the previous owner cut the gray wire and spliced one to a green wire and the other to a black wire. I connected the gray wires back together and now it works on hi and lo. but now i don't know what the green and black wire were for, but at least it works now.
