I have an issue with the wipers not wanting to turn off after they are turned on. When I would want a quick wipe, i'd flick them on and off since there is no "mist" function.

Then they started to not turn back off and I had gotten good at twisting the control on and off to get it to turn off. Now it takes me turning off the whole car to get them to turn back off.

I had replaced the control inside the explorer and checked the fuse for the wipers and it is intact. Must be since they turned on in the first place. Please help, want to get everything fixed to either sell of drive again.

WIPERS RUN WITH SWITCH IN OFF POSITION Unplug wiper control switch. Turn ignition on. If wipers park, replace wiper control switch. If wipers continue to run, check interval governor and wiper motor. See WIPER MOTOR CURRENT and INTERVAL GOVERNOR TEST under TESTING.
WIPER MOTOR CURRENT 1. Disconnect negative battery cable. Disengage linkage from motor. Unplug wiper connector. Connect Green lead from Starting and Charging System Tester (078-00005) to positive battery post. 2. Connect Red tester lead to low speed connection (White wire on mating connector). Observe ammeter. Connect Red tester lead to high speed connection (Dark Blue/Orange wire on mating connector). Again observe ammeter. See Fig. 2 . Motor current draw should not exceed 3 amps for either measurement.

INTERVAL GOVERNOR TEST If interval operation is not correct, check wiper motor current draw, wiper control switch, and all connecting wires for continuity. If these components and wiring are okay, replace interval governor.
WIPER SWITCH Check for continuity between switch terminals. See Fig. 3 . See WIPER SWITCH CONTINUITY table. To detect marginal operation of switch, move switch lever while making measurements. If continuity or resistance is not as specified, or if continuity is poor in any position, replace switch.
