In my Ford Expedition, the rear wiper function is on the regular windshield wiper wand about half way down, toward the steering wheel. If you twist the little black knob(??) down, it will activate the rear wiper fluid feature, twist it up and it will give you a few intermittent options.
The switch for the rear wiper is on the same lever as the front wipers. It's a circular switch that turns forward & backward.
The switch for the rear wiper will be on the dash, to the left of the steering wheel.
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.
If the rear wiper on a 2001 Isuzu Rodeo will not turn off it could mean that the rear wiper switch is broken. The cost to replace the switch averages around $200 if done by a professional mechanic.
Push the wiper stalk towards the dash.
push the wiper lever away from you. this washes the rear windscreen and starts the wiper. push the lever away from you again to stop the wiper.
Switch or the park switch in the motor.
The switch just pops out of the dashboard.
rear wiper, rear defrost
When I hit the blinker I accidently moved the switch...sorry.
rotate the right stalk forward
Remove the dash bezel, remove the switch, reverse process with new switch.
