97 jeep cj windows and wipers stopped working fuses are ok


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.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service
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,,

Winshield wiper delay intermitent module making noises


The wiper delay is in the steering column. It's a small box about 2 x 2 inches with a wiring harness attached. With the testing procedures I found below, you should be able to figure it out. I found wiper delays on eBay for around $10 to $20. Good luck.

WINDSHIELD WIPERS CHEROKEE, COMANCHE & WAGONEER 1. POWER INPUT Remove circuit breaker. Test battery side of circuit breaker. If battery voltage is not present, repair open to splice. Test across circuit breaker terminals. Tester reading should be zero (0) ohms. If not, replace circuit breaker. 2. GROUND Connector A unplugged. Test terminal G. Tester reading should be zero (0) ohms. If not, repair open to ground. 3. INTERMITTENT WIPERS Ignition switch in ACCY. Remove delay module and plug connectors together from the module. If wiper operate in LO and HI speed modes and mist (washer) is working, if wipers and mist operate, replace intermittent module. If not go to step 4. 4. WIPER/WASHER SWITCH Ignition in RUN, wiper switch position as indicated, back probe switch side of connector A for standard, connector B for intermittent: Test connector terminal E-wiper switch in LO and mist/intermittent. If battery voltage is not present, replace switch. test connector terminal C-wiper switch in HI. If battery voltage is not present, replace switch. Test connector terminal F-wiper switch to OFF. If battery voltage is present until wipers stop and then voltage drops to zero (0), system is working fine. If this does not occur, replace switch. 5. INTERMITTENT WIPERS Connector B unplug. Test across terminal A and D while rotating switch from minimum to maximum delay. If tester reading is not between 0-500 ohms, replace switch. Test across terminal A and G while rotating switch from minimum delay to maximum delay. If tester reading is between 0 and 500 ohms, replace wiper module. If not replace switch. 6. WIPER MOTOR Ignition in ACCY, wiper switch position as indicated, probe connector D. Test connector terminal 1. If resistance is no zero (0) ohms,repair open to ground. Test connector terminal 4-wiper switch in any position. If battery voltage is present, replace motor. if is not repair open from fuse panel. Test connector terminal 2-wiper switch in LO. If battery voltage is present, replace motor. If not , repair open from wiper switch. Test connector terminal 2-wiper switch in HI. If battery voltage is present, replace motor. If not , repair open from wiper switch. Test connector terminal 5-wiper switch OFF with voltmeter connected. If battery voltage is present until wipers stop and then voltage drops to zero, system is OK, replace motor. If not, repair open from wiper switch.

I have a hard top for a 1990 jeep wrangler and it has a rear defroster and wiper. This might be a dumb question but should there not be controls for these and if so where at. I have a chiltons book for it...


So the Jeep has a hard top....... or you bought a hard top to put on your Jeep that originally did not come with a hard top. You can forget Chiltons for good info. If there is no switch, the wire harness may/should be there, so you need to install a switch and relay. The harness ends up at the left tail lamp area. The relay is up above the parking brake pedal. 5 wires. Brown. Brown/White, Black/Yellow, White/Black, and Black (ground) The harness should be there to connect a rear wiper switch in the dash.

Delay wipers don't work.


Try making sure the connection is good.
If it is then you should try replacing the wiper switch.

94 YJ Wiper


Do you have a test light /probe to check that you have power at the wiper motor?If not swap one fuse at a time with same colour and amp rating until you find the dodgy fuse,if there is one.Did you check the old wiper motor to make sure it is no good as the wiper motors dont usualy give trouble and to have two in a row fail usualy implies that there is another problem.It may be the switch.
