Wipers at Hi and Lo speeds work; so does intermittent wipers. However, a clicking sound from behind the glove box starts and the wipers will stop and go or retract and not come back up until the clicking stops or sometimes stop working completely. Turning off the wipers and back on will make the wipers work in all functions until the fast clicking starts and then the wipers start jumping around. Do I need a new wiper motor or wiper/turn signal switch at the steering column or both? Thank you

Re: Wipers at Hi and Lo speeds work; so does intermittent...
Check your charging system! That sounds like low voltage starvation. If a weak battery has a heavy load on it, such as a wiper motor, the electromechanical relay may drop out or "buzz," which interrupts the circuit at high speed, stopping the wiper because there is insufficient current available. You could simply have dirty (or corroded) battery connections!

Do you know what a wiring diagram is ? A wiring diagram for your vehicles windshield wipers electrical circuit would show all components involved . You would need a wiring diagram for testing ,so you know which wires too test . It would show the fuse location - amperage etc.... Which of these is your vehicle - Notchback or hatchback or station wagon .
The fuse would be marked WPR fuse # 9 25 amp. located in the IP fuse panel . IP - instrument panel fuse box . It's location is
Fuse Block - I/P
Behind the left side of the I/P access panel
Windshield Wiper System
The windshield wiper system consists of a wiper motor, a linkage, a wiper arm and a blade, and a wiper/washer switch. The windshield wiper circuit incorporates a self parking device which consists of a worm gear and a cam plate in order to keep the circuit engaged temporarily when the switch is turned off. The wiper system is driven by a permanent magnet-type motor. The windshield wiper motor is mounted on the dash panel and is directly connected to the windshield wiper linkage.
The windshield wiper motor has 2 speeds, LO and HI, and also has intermittent wiper capability. The wiper switch is an integral part of the wiper/washer switch. Windshield wiper operation is actuated through the lever on the right side of the steering column.
Could be the motor, or the actuator arms binding. You will have to remove the cowl cover and observe the arms in action. make sure the connector grommets are present and in good condition. If so , probably motor is overheating and tripping circuit breaker.
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.
it would be the relay. don't know this model well but it is usually behind the fuse box. it is a speed control relay with timer in it. intermittent control and speed 1-3. or 4 on some models. when pipers working should hear it clicking on intermittent setting on wiper.
does the same thing in my 01 expedition, they are famous for it. you (we) will eventually have to replace the switch in it, sounds like urs might be on its last leg!
Alarm control unit has a chip in that controls the delay wipers, this chip cost about 2 dollars, but it has to be sodered in. the whole box cost about 200 dollars. It is located behind the glove box on above the right kick plate ive been told. chip can be bought from mouser.
I had the same problem with my 93 Lumina and then it would work ramndomly then quit Wiper motor was the problem Changed all fuses first to no avail Wiper motor fuses are under the glove box behind the coweling as well as in the fuse box beside the glovebox for info
