It is most likely next to your fuse box inside the car or the fuse box in the engine compartment.

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?

If you have power to the wiper motor and the motor will not come on then your wiper motor is bad. When the wiper switch is off their should be no power to the motor. When the wiper switch is on, power is sent to the wiper motor and the wiper then turns on. The relay is use probably to control the wiper speeds you select. I hope this helps.

2005 Jeep Grand Cherokee font wiper problems. wipers will not park all of the time. when you start Jeep or shut off vehicle, wipers will cycle once. switch is in the off position. dealer replaced wiper...

both blades fail to park.?
are the arms installed correctly?
so the wipers run , when you key on. ? is that it
tell me when exactly they move, and you didnt commend it.
here is how i do this, i log in to
and see its a complex set of 5 parts, in the wiper schematic
2 relays (on/off and hi./low) and the wiper motor and the switch
and the controller.
so i take my handy voltmeter ($10 at walfart) and measure
pin 30 of the wiper relay on/off.
if it reads 12vdc (keyon, or off, with wipers off) this is a bad reading
if it reads 0v, , its good. easy huh
but what if the relay 30 pin read 12v
what would i do, id see if its being told to turn on.
id pull it out, is the wiper dead now. (yes, might be bad relay)
but id check the voltage across the 85/86 relay coil pins
12v is bad, the IPM is commanding wipers full time. (keyon)
0v is good, and relay is TOAST>

The IPM is the thing that holds the wiper switch.
it too can fail but i bet not.

How do you troubleshoot wiper blades on a 1995 Jeep Grand cherokee?

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.

Intermittent Wiper Relay Where is it located on a 1999 Jeep Cherokee?

look under the hood for main engine fuse box. should be a black box that contains the main engine fuses and lid and on the underside of the lid look for the wiper relay location.if your wipers are'nt working,check the fuse for the wipers also.if your wipers work on full speed,your problem may be in the wiper switch itself. thank you for choosing

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.

Try running yoor own ground wire directly to the wiper motor or the wiper motor mount,this woks 80% of the time.

I have a 93 jeep cherokee that for some reason the wiper motor will not work can you help

Check if there is power going to the wiper motor when wiper switch is turned on,you can use a multimeter or test light,if not check fuses,wiper switch and wiring.
If there is power at the wiper motor,most likely you need a replacement unit.
