Weird Rear Wiper

Having problems figuring out why my rear wiper quit working. The rear defroster works which tells me the wiring is fine. The switch controlling the wiper/washer----the washer works but the wiper does not. I purchased a rebuilt wiper motor from a local auto parts store. I plugged it in before installing and that one did not work either. Is it possible that rebuilt unit was bad? What else can I try? Purchase another wiper motor from a different source? Help cause winter is coming!!!!

Check the switches in the rear hatch flipper glass if your jeep has it, as well as the switches in the hatch itself, if the switches that tell the jeep the hatch is open are bad, it won't allow the wiper to work at least in my 98 ZJ that is the case. If I open the hatch with the rear wiper on it stops the wiper and returns it to the park position. I have the opposite issue my rear defrost don't work but the wiper does LOL.

Have you checked with a test meter to make sure you have power being fed to the wiper motor? If I'm thinking right, the wiper and washer run off of independent wires. Both passing through the same switch of course, but separated. If not, I would start there. With the motor unplugged, probe the incoming pins while the wiper is turned on.

year, model?

Why do you ASSUME wiring is good? With a diagram we can do a quick check,

When I see the price of OEM I think aftermarket.
When I see the quality of aftermarket I think OEM.
