So my wipers went out on my 84 H/O. I noticed the ground strap was broken on the wiper motor so I purchased and replaced the wiper motor. Wiper still didn't work. I pulled the motor out and checked the switch and all the wires on the column switch on and off like they should. I thought the problem could be the pulse board, so I ordered a spankin' new one from Monster Auto Parts. Plugged it all in and it doesn't work. I pulled the whole thing off and checked the wires again and they switch correctly, then I thought to check the wires when it was plugged in. Instead of the wires showing "off" and switching to positive with the wiper switch to turn on the motor, they all show positive when the motor is plugged in??? So Is it a bad motor or pulse board? They are both brand new??!! Any suggestions?

I haven't tackled it yet on a GM (mice ate my whole wiper harness) but the ground strap is a very common issue on the Mopars. I've owned 3 cars and known half a dozen others that were diagnosed as needing a new wiper motor, when a simple ground strap solved the problem. If in doubt, run an auxilary strap from the motor casing to the body or frame of the car. This is also a big help on alternators. 
yes i did fix the ground strap. The ground strap is a small brass strap bolted to the housing and affixes to a bolt. I have checked the strap with a test light and it shows ground.
Have you tried connecting direct power to the motor to see if it works?
Here is a link to another forum. This person was having problems with the wipers, its not the same problem as you, but you might be able to get some info out of it.

Ok, so I tried the wires with just the motor plugged in, and the motor just makes a click sound and nothing else. So, I think the motor is bad. We will have to find out tomorrow.
I thought this forum would have some guys who knew a little more of g-bodies. I am a little disappointed.
Thanks for the link though, not too much help for my prob., but thanks.

well I am trying to get help with this, and it falls under all the areas I posted it in. I am just really trying to get some help. Sorry, but I thought that is what a forum for a specific type of vehicle can be used for.
