Several possibilities are that:
1 the switch is bad on the high position.
2. There is a problem with the high speed wire from the switch to the motor.
3. The wiring inside of the wiper motor for the high speed is bad.
The way 2 speed wiper motors work is there are separate windings inside the motor for low and high speeds. Usually 2 wires come out of the motor for low and high and the common ground through the wiper motor body to the chassis of the vehicle. You apply 12v to one wire and get low and 12v to the other one for high speed.
Because they are BROKEN
why don't the windshild wipers work on 1995 ford countours. their is no power to fuse box or wiper motor.
Check the fuse for the wipers. Otherwise the wiper motor is probably done for.
we have the same problem. let us know when you find the answer
If your 1992 Camry Wagon rear wipers do not work, it could possible be the motor. Be sure to check the motor as well as the fuses for any issues.
If on the same circuit, it may be the fuse.
2000 expedition wipers & radio don't work when in drive
there are three things it could be a fuse, relay, or the wiper motor itself
some times wind shield wipers dont work because the car is frozen and they need to thaw out from not moving for a while. if it gets to be a big problem go and buy some sleeves for them.
You need to replace the wiper motor.
try checking the switch
try checking the fuse. check the plug that goes into the wiper motor.
