I have the same issue on my 98 Suburban. I left the wipers in the on position and then lifted the hood to get at the electrical connector to the wiper motor, once I gave the electrical connector a wiggle the wipers started working again. Get an Auto Electrician to replace the connector = problem solved.

2005 ford escape wiper and washer has no power. cant hear it engage when on but was working a week ago. how can i troubleshoot it and find the fuse


Hi Justin , Do you know what a SJB - smart junction box is and where it is located on you escape ?
Windshield Wiper Operation
The smart junction box (SJB) supplies power to the multifunction switch from the SJB fuse 25 (20A) when the ignition switch is in the ON or ACC position. The multifunction switch supplies power to the windshield wiper motor for the HIGH or LOW/INTERMITTENT input, depending on the multifunction switch position selected. The SJB also supplies power directly to the windshield wiper motor from fuse 25 (20A) when the ignition switch is in the ON or ACC position for RUN/PARK operation. When the multifunction switch is in the LOW, HIGH, or INTERMITTENT position, power is supplied to the windshield wiper motor, which moves the wipers off the park position. Once the wipers are off the park position, an internal switch in the windshield wiper motor switches to the run/park position which directs power to the wiper switch then back to the wiper motor. This maintains power to the windshield wiper motor to complete the wipe cycle. When the cycle is complete, the internal switch in the windshield wiper motor switches back to the park position. If the multifunction switch is in the LOW or HIGH position, power is supplied from the multifunction switch and another wipe cycle starts. If the multifunction switch is in the INTERMITTENT position, the windshield wipers remain parked until the internal relay in the multifunction switch supplies power to the windshield wiper motor. The internal relay supplies power after a time delay that is determined by the 1 of 9 intermittent switch settings.

My windshield wipers wont work.


It Sounds Like, Either The Arms Are Loose ,If You Can Hear Something Moving Behind The Dash,
Or The Linkages Are Seized ,If The Motor Just Hums No Movement Heard,In Which Case Try Spraying Q 20 On The Linkage And Try Moving The Wiper Arms By Hand To Get It Going Again,
If Not The Motor May Just Be Burn;t Out.

The windshield wiper does not run, but i can hear a humming when i turn it on. I was told that it may need some kind of module.


It sounds like you may have a broken drive from the electric motor or the linkage to the wiper arms have broken.. The only way to tell for sure is to strip out the wiper motor and the linkages..which can be a big job and can entail removal of several other parts first.. Try moving the wiper arms manually, with your hands.. If you can move the wiper arms across the screen then the linkages have broken and will need to be replaced as they are not a repairable item..

1988 nissan civilian. Intermittant wipers dont work. Wipers dont return to park position when turned off.


Hi, sounds like your wiper switch has died, it's what I'd look at first, maybe talk to a wrecker & see if you can buy one, if it fixes the problem, good, if not take it back and get a wiper motor, though I don't think it'll be the motor as it should just stop altogether, hope this helps :)

Wipers won't stop wiping.


Sounds like your intermittent wiper circuit is defective. Normally the intermittent feature is engaged by one of the functions on the multi-function switch (usually on the steering column). The circuit of the intermittent wiper periodically activates a relay that closes across the "Wiper On" switch. Your intermittent wiper circuit is likely defective and holding its relay closed (or the relay is stuck closed), thereby keeping the wipers on. Note: The wiper motor has an internal switch that opens when the wipers are in the park position and that is designerd to stop the wipers in the park position. When you turn on the wipers (or the intermittent relay is closed), the motor's internal switch is shunted such that the wiper does not stop at the park point of the cycle.

Volvo V70 (53 reg) rear wiper has stopped working. Can hear motor trying to turn it but wiper blade doesn't move? Is this something simple I can fix myself?


no you would have to pull the motor to make sure its working but it sounds like what you may be hearing is like a humming sound where its trying to work but not.
