Heads up on your motor - It is probably still good.
I'd like to give some advice for those in my similar situation.
Here is what I had/have:
My new rig and the wiper would not turn on from the dash switch! Wiring looked good but it wouldn't budge, not even a lerch.
my advice - remove the entire wiper assembly as one entire peice. Remove the cover to the main wiper (that's the one on the passenger side. Cover has like 6 screws. Remove the 2 snap rings on the gears that connect the 2 wipers together.
This is done to isolate the motor to see if your motor is working. If your mechanisms get fouled up with crappy old grease or sticky from lack of use, the motor could be fine, but not strong enough to overcome the old grease and crap (like mine).
We need to test the motor - cuz if the motor is bad, then I need to find a new one
Now test the motor by running a wire off your battery to your motor connector. There will be 4 wires in the connector. then "Connect +12V to the solid blue wire on the wiper motor. Then GROUND the Blue/Black wire for HIGH and then ground the Blue/Red for LOW. Do NOT ground both at the same time!!!" I got this from a dude with a handle of COOLERMAN earlier post.
Just strike one to the other and look for sparks or motor movement. It should turn or lerch. if it lerches when you strike, then the motor is good. NOW clean out all the gunk and lots of 3in-one oil to get everything moving. now invest in getting all the old grease out
now start disassembling and cleaning and painting and reassembling and re-installing.
Thanks to Dude Coolerman for his previous post.
I cam post photos if I get to it tonight. I won't waste your time if no one is interested.
