They are both located under the plastic wiper cowl in the area between the hood and windshield. Remove the wipers (if you aren't sure how to do that you pull the tabs about 3/4 of the way out) then you remove the screws in the wiper cowl. Once it is removed you should see both the wiper motor and control bar.
ITS WITH THE WIPER MOTOR ITS ALL ONE UNIT
Things can cause this problem. The wiper motor itself or the wiper control module may be bad. Also the switch or bad wiring. It is a process of elimination.
rear wiper, rear defrost
you have to remove the panle on the outside of the jeep between the hood and the windshield. 4 screws.
It should be for the rear wiper or rear defroster. I have a 1992 (no power switch), but on the left side of my column are the fog light and rear defrost switches, and on the right is the rear wiper switch.
I have a 99 Jeep Wrangler Sport. My wipers would somtimes work, other times not. Now they don't work at all. Checked the fuse and replaced the switch with a brand new one, still nothing. My guess, if you have the same problem, is that the wiper motor has burned out.
The heater vents above the stereo can be easily pried out. This should expose the mounting screws for the panel.
The 2007 Jeep Wrangler takes a special jeep-only, dealer-only rear wiper blade. Its best to ask the dealer for the procedure when you go in to buy the replacement blade.
The three wires are the ground wire, the hot wire that runs through the switch and is energized only when the switch is in the on position and the third wire which is energized anytime the ignition switch is on. This circuit allows the wiper arm to go to the "park" position when you turn the wiper switch off. If you turn the ignition switch off while the wiper is in operation it will stop immediately and not continue to the "park" position. When the ignition switch is turned on again, the wiper will return to "park".
look at the half circle clip on the side of wiper arm. lift the wiper arm and pull the clip out as far as it goes the wiper arm should rest on the clip and now be "locked" up in the air . now you should be able to remove the wiper arm
try replacing the wiper switch....hope it helps
