Working on a 2000 jeep grand cherokee. front wipers do not work. fuse is good. have power and ground at motor. 2 new relays in onoff and highlow cavities. new wiper switch at colomn. what am i missing?

97 wrangler right? CJ ended in 86 (last year)
97 TJ, you mean, or was posting to Cherokee correct all along./?????
factoid:
The Chrysler Corporation bought out AMC in 1987, shortly after the Jeep CJ was replaced with the AMC-designed Jeep Wrangler or YJ.


test the fuse, looking only finds the ones blow to H3LL
they can in fact just crack a bit. and are in fact bad.
use any DMM or any ohmmeter, "resistance Rx1 or RX2 range , low range) 0 ohms good, , infinity bad.
only that works. every time.
lets read the FSM together.

wipers first. USA not export.
Front wiper not rear. ok>?
page 8w-53 wiper schematic.

fuse 2 and 3 must be good.
then fuse 14 front wiper ,fuse 12 is rear
if the fuses are good, (truely) we never ohm fuses we use VOLTS
on both sides of fuse, volts never lies.
then what is bad, easy bad wiper switch, motor or ground to motor.
the voltmeter again wins the toss and if no 12vdc to motor
then the switch or wire are bad.
if you have 12v to motor then motor is bad , if ground to motor is no cut.

now windows. what windows, are then not crank windows or zipper windows?

i think you posted wrong car,,

join a grand cherokee forum by googleing it and post this and all future questions there

Check your manual for wiper fuse & relays location.You can inspect fuses visually...hope this helps

First check the wiper fuse then check the relay by turning wipers to on position and listen for the relay to click if it clicks its good.If they are good then turn the ignition and wiper switches on and check for 12 volts at the wiper motor.If you 12 volts then the wiper motor is faulty.Replace motor.

if the fuse failed then that means one of few things...

1.) motor has failed causing excessive current draw
2.) circuit has direct short to ground
3.) short to ground that caused fuse failure is now an open

you need to check for power and ground at the wiper motor

keep us posted

The power distribution center is on the left side of the engine compartment near the front. The wiper relay is in there and it could have failed and not the fuse. The wiper fuse is in the same area. You can substitute the wiper relay with another one that has the same part # in the dist. center box. That is if the fuse is good. Lastly, don't assume the fuse is good when you look at it. Test it with an ohm meter or use a known good or new fuse.
Good luck, Rudy

You have a motor for the front and rear washer. Check the fuses. If the intermitted wipers does not work, there is a relay under the dash near the steering colum that needs to be replaced.

Check ground wire on wiring harness to wiper motor. If ground is good you need a wiper switch. Good
luck

Check fuse, relay & motor for power.If it happened all of a sudden it is likely one of the three.

hi if you have changed the switch and the wiper motor and all the fuses are ok you only got the wiring and what is favourite the wiper relay switch try this first its cheap and is a problem on all cars not just yours if it fails to work i can give you some simple tests to find out what is or not working good on ya at least your having a go yates210456
