I have a 89 jeep Comanche 2wd 4.0, and the wipers just decide stop working, when I turn on the wipers I hear a noise coming from wiper delay intermittent module, I though I have to replace it but plug in off and on the 4 relays under the hood make the trick, but I find out these are nothing to do with the wipers, should I replace the wiper delay intermittent module any way? or where is the wiper relay to check it out or replace it?
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.
Found on the web. I hope this helps.

All the relays for the wipers are on the motor under that black cover. could be the multifunction lever switch on the left hand side of the steering collumn is bad, the yellow wire would break and no wiper operation. you can remove the little cover behind the turn signal lever and check the wiring(especially the yellow one). also try pushing on the wiper motor cover to see if it comes on. if not try probing a test light in the back of the connector on the motor while hooked to ground and this should trigger the motor to come on in different speeds if the key is on.
Good luck

Check if u have power going to the motor first.If you have then your switch is faulty.

hi !
I don't think that has anything to do with the brake pad and rotors.

It could definately be the wiper relay, and it could also be the wiper motor. If you put a long screw driver on the relay and have someone turn the wipers on with the key on, you should be able to hear the relay clicking as it opens and closes. Sometimes you can put your finger on the relay and feel the relay switching. If you can hear/feel the relay then the next step is the wiper motor. Hope this helps.
