Why is my back wiper not working?
The windshield wiper fuse is burnt out. If the wiper motor fuse burns out, check for any obstructions that may cause the motor to be overloaded. Heavy snow on the wiper blades or a wiper blade or arm caught on something or snagged together can cause the fuse to blow. Clear the obstruction and replace the fuse.
Is there a fuse for washer fluid?
If you don’t hear the washer pump running when operating the washer switch, the first step is to check the fuse. You can find the location of the fuse on the fuse box cover or in the owner’s manual. The fuse says “Washer,” see the photo. In most cars there are at least two fuse boxes.
How do I know if my rear wiper motor is bad?
Symptoms of a Bad or Failing Windshield Wiper Motor
- Wiper blades move slower than programmed.
- Wiper blades only have one speed.
- Wiper blades don’t move.
- Wiper blades don’t park in the correct position.
How do you test a rear wiper motor?
Unplug the wiper motor connector. Probe the voltage supply plug with a voltmeter and make sure voltage and ground are present. Move the wiper function switch through all positions to determine proper voltage at the plug. If there is no voltage, check the voltage supply to the dash switch and check the rear wiper fuse.
How do I reset my rear windshield wiper?
Use a socket wrench to remove the nut located at the center of the wiper motor. This nut connects the arm linkage to the motor. Turn the wipers on, then back off, so the motor completes a full cycle and returns to the correct park position. The blades will not move since the linkage has been disconnected.
How do you test a rear wiper relay?
Check for voltage input to the rear wiper relay by removing the relay from the panel and measuring voltage at the appropriate socket terminals with the ignition on. If there is voltage input to the relay but no voltage reaching the motor, then the relay is faulty and should be replaced.
Where is the washer fuse?
One fuse sits in the power cord to the washing machine and will blow if a power surge reaches the washer. The other fuse sits in the lid switch on some machines; if the washer overheats or there is a power surge, the washer will not run again until the fuse in the switch is replaced.
How do I reset my wiper motor?
What do you need to know about Chrysler minivan wiper problems?
Diagnostics > By Symptom > Electrical symptoms > Chrysler minivan wiper… Chrysler Minivans have more than their share of wiper problems, ranging from wipers that won’t shut off to intermittent wipers that quit working. If you have Chrysler minivan wiper problems, all you need to diagnose the problem is a digital multimeter.
Why is my wiper motor not turning on?
If you get ground, that confirms the FCM is receiving digital data from the controller and is acting properly. If you don’t get ground, the problem can be a faulty FCM, a corroded IPM or TIPM (very common) or a short in the data bus. As I mentioned, the MFS doesn’t switch power to the wiper motor.
How does the front wiper on / off relay work?
Power flows to the control coil side of the front wiper ON/OFF relay from a fuse that’s hot all the time. The control coil now has power, but no ground. The front control module (FCM) housed in the Integrated Power Module (IPM) or Totally Integrated Power Module (TIPM—used in later models) is what provides the ground to the ON/OFF relay.
What to do when your wiper is in intermittent mode?
The BCM sends voltage to the park switch on the dark green/white wire and when the switch closes, the voltage should drop to zero. So attach your volt meter to the dark green/white wire and a ground and watch the voltage while the wipers are in intermittent mode.
