SOURCE: windshield wipers won't stop running

It could be the washer switch is bad. If you have intermittent wipers the control circuit is probably bad. Lee

SOURCE: Windshield Wiper Only Works On High

There is a wiper speed control module or governor behind the instrument cluster. You can check with the dealer on price and what it looks like. It controls everything but high speed.
You should be able to do a circuit test on it to see if it is working. The low speed side of the motor may be bad too.

How do I find out if the wipers on my 2006 H3 Hummeris on a relay?


The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper micro relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIP/WASH 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper micro relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay switched output to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

Low Speed Operation
When the wiper switch is in the Low position, voltage is supplied through an internal resistor to the signal circuit. The body control module (BCM) monitors the windshield wiper switch signal 1 circuit, and energizes the wiper micro relay which will operate the windshield wiper motor. The wiper motor will operate at low speed, since the wiper 2 relay is de-energized. Low speed can also be commanded with a scan tool, by commanding Wiper Relay Cmd. ON and OFF. Refer to Scan Tool Output Controls .
High Speed Operation
In the High position, the windshield wiper/washer switch supplies voltage to both the wiper micro relay and wiper 2 relay coils. This energizes both relays and allows battery voltage from the wiper micro relay switched output to the switched input of the wiper 2 relay through its contacts and out the switched output of the wiper 2 relay to the high speed circuit of the windshield wiper motor. The windshield wiper motor will operate at high speed. During high speed wiper motor operation the wiper switch signal circuit is at the low speed signal voltage, and the body control module (BCM) supplies redundant voltage to the wiper relay via the wiper diode.

How do I fix the speed of my windshield wipers, they only work on high speed and I have replaced the windshield wiper motor and that did not help?


In that year they used a wiper control module and the switch to control speeds and delay interval. The part is obsolete at the ford dealer and you may have to resort to salvage yard for part.

What would cause the windshield wipers on my recently purchased Jeep Patriot Sport work on every speed except the high speed. High speed doesn't work at all.


The intermittent switch has a bad contact in it for the high speed, i would say, most likely will have to replace it.

Wipers only work on fast. Checked the relay and its good, checked the switches and its good. What else needs to be checked?


This is (obviously) a two-speed motor. The low speed winding is burned out. Replace the motor.

WIPERS


My wife complained about the same thing on her BMW. After driving it on a long road trip in the rain, we realized that if you just turn it to the first setting, the wipers automatically speed up, and slow down as rain increases/decreases.

two separate switches normally have two separate fuses.voltage drop test wiper ground.also check switch output at different speeds. this vehicle may have control module and/or relay by itself or with the module. if output is at switch,intermediate component is the problem.
