1991 cherokee briarwood

Rear wiper is clicking but not turning.
Replaced with Napa motor/relay and same deal.
Washer fluid works fine.
Fuses seem in tact.
Get 13ish volts when motor is trying.
Black wire is grounding fine.

The clicking is happening in both motor relays. Am I missing something?

People use the rear wiper?

Is the motor doing anything? You have power at the motor?

Remove it and use the wiper fluid as a weapon when some one is tailgating you, that's what I do.

Yes. Why wouldn't I use it? The brown wire is getting power. Ground is good. Relay is just clicking on both motors. Everything above is what I've done so far.

Dumb question, did you check to make sure the teeth on the arm are in tact? Could be turning fine and just slipping at the arm. Good luck

I don't think I've ever used mine.

This was going to be my next suggestion.

double post

I don't have a rear wiper. Wasn't on it when I bought it. I have no clue where it could be. The cool thing is, my windshield washing fluid shoots straight back about 4 feet without it.

Also, make sure the harness that runs between the body and top of the hatch is in good shape. They tend to get a bit rough from movement. Really high resistance would pass the voltage but wouldn't handle the current. Granted, it'd probably be smoking.

I have no issue with people that don't want their vehicles performing how they should with all the things they should but I like having mine in working order. Something simple like this shouldnt be a difficult fix thats why I asked the forums.

The teeth are good I unhooked the wiper arm and watched for it to turn.

The connection I would hope is good since I'm getting a voltage reading from the brown wire when I use a voltmeter on that and the black wire. Should I be getting a reading from another wire when its on also? I assume the grounds are good since I'm using it to check the voltage output on the brown wire.

I'll check that next Lowrange. Thanks everyone anymore suggestions would be great.

Also, parts have been known to not work out of the box from time to time. Test the motor outside of the Jeep.

Ok tried this.

Pulled the old motor and hooked it up to ground direct to the battery.
Used a jump wire from positive to the brown. Nothing but a spark
Hooked jump wire from positive to green and the thing started going.
Put the relay (if anyone has the part number for this I would appreciate it) back on and hooked it up to the brown wire. Clicking.
Left the jump wire hooked up from positive to the brown wire then after the relay i jumped the brown and green and BAM thing started working.

Does this mean the relay is bad since its not sending the power to the green wire from the brown?

I have seen times when a bad ground would carry enough current to make the proper voltage appear on a volt meter, but once you place the load of a motor inline then it can no longer carry the voltage. Have you tried using the volt meter between the motor terminal and the ground terminal to see if the current is flowing all the way through the motor to ground?

Alright, according to my manual that's in my lap you should have ground on the black wire going to the motor.

There should be a white wire that goes to the wiper relay. It should have a positive 12 volts when the switch/relay is active.

There should also be a blue wire. It should have a positive 12 volts all the time.

2 hots and one not.

I'd guess that you have a bad relay.



All these wire colors should be at the motor.

This is how it works here.
