Then check for continuity across the relay switch contacts. If no continuity, as the solenoid is powered, then the relay is bad. If you suspect the switch, simply turn the switch “on” and check for 12 volts from the switch output to any body ground. If 12 volts are not measured, then the switch is bad.
As with any electronic component, it can fail completely or only on one circuit. Your wiper relay could be bad if the low and high speed wiper positions function properly but the intermittent function stops working. Any combination of positions working or not working is a good indication of a faulty relay.
Similarly, is there a relay for windshield wipers? Although many vehicles do not have them, a wiper relay switch operates when you turn on the wipers. It closes contacts that provide voltage to the windshield wiper motor.
In respect to this, what does a windshield wiper relay do?
The Windshield Wiper Motor Relay is a part of your windshield wiper system. It controls the voltage input to the wiper motor. The relay senses the position of the wipers and transmits power to the wipers they are in their parked position.
How do you change a windshield wiper relay?
Part 1 of 1: Replacing your intermittent wiper relay
- Materials Needed.
- Step 1: Locate your relay. Many late model vehicles can have multiple locations for fuses and relays.
- Step 2: Remove the relay. With the ignition in the off position, remove the relay.
- Step 3: Install the new relay.
Where is the wiper relay?
The wipers are controlled by a relay located at the top left of the under dash fuse panel. On the Integra, the function is controlled by the integrated control unit located in the fuse and relay panel at the left kick panel. The Legend uses a relay located in the center of the relay panel in the engine compartment.
How do you reset windshield wipers?
Resetting the wipers involves removing the wiper linkage and manually placing the blades in the right position. Remove the plastic cover between the hood and the windshield that hides the wiper motors and arms. Use a socket wrench to remove the nut located at the center of the wiper motor.
What fuse controls the windshield wipers?
The windshield wiper should be a 25 amp fuse at the top closest to the windshield. There should be a little plastic tweezer looking tool to use to pop it out.
What is a wiper control module?
The windshield wiper module, or governor, controls the wiper motor operation. The module receives input from the wiper switch, and in some cases from various sensors as well. It is responsible for determining wiper speed and parking.
How much does a wiper motor cost?
The average cost for a windshield wiper motor replacement is between $339 and $406. Labor costs are estimated between $80 and $102 while parts are priced between $259 and $304.
Why are my windshield wipers not turning off?
Faulty park switch: Inside the wiper motor is a park switch. If this switch goes bad, then an electric current will go through your windshield wiper system even when it is turned off. Bad wiring: A loose wire or bad connection could also cause your windshield wipers to continue to run even when they are turned off.
What causes windshield wipers to work intermittently?
If the problem is not in the switch, then there could be a bad relay in the circuit (if so equipped), loose fuse, bad ground, and/or the motor could have a bad (intermittent) connection on the armature. Also, of course, you could have a combination of these electrical faults.

How do I know if my windshield wiper fuse is blown?
Solution: Check your owner’s manual for the location of your fuses, and to identify which fuse protects the wiper motor. Pull out the fuse and inspect it — if it’s blown, you should be able to see a broken wire inside it, or char marks. Replace the fuse and see if the system operates properly.
How do I know if my wiper switch is bad?
Windshield wipers won’t turn on or off. When you turn the windshield wiper switch on, the wipers are supposed to move from drivers left to right in a curved pattern. Windshield wipers do not change speed or settings. Turn signals not working.
