Why are my windshield wipers running so slow?
When I lifted the blades from the windshield, they ran, but still very slowly. What would cause this? A few different items can cause the windshield wipers to work slow. The most common causes are the windshield motor beginning to fail, poor electrical connection at the windshield motor, or high resistance at the wiper motor.
What kind of motor does a windshield wiper use?
Windshield wipers are powered by a motor that receives 12-volt power through a switched wire. Complete failure of the wipers to work can be a complicated troubleshoot, but working with a motor that still runs on one speed is less challenging. Diagnosis can be time-consuming, but it is not complex and requires only one tool.
How can I get my windshield wipers to work?
Trace the ground wire from the motor to its mounting point, then scour both the underside of the connector and the mounting point on the chassis with very course sandpaper — 60-grit or heavier is recommended — then replace, ensuring the fastener is securely tightened.
Why does my high speed wiper still work?
That the high speed — the least frequently used — selector still works suggests the tension has gone from the low and intermediate speed contacts. If they can be accessed and bent to create more tension this is a temporary fix at best; replace the switch. Having ascertained that the switch is good, test the wiring harness.
Can a windshield wiper get stuck in the middle?
Windshield wipers move slow and get stuck audi windshield… My windshield wipers started moving really slowly while it’s raining. I didn’t think about it for a while because it’s been dry, but today I tried to turn them on with a dry windshield, and they got stuck in the middle – just partially up.

Why do my intermittent wipers not turn off?
My intermittent wipers work fine, as does the low speed, high speed, squirting function and single wipe, but once any of these are activated the wipers remain on when the switch is in the off position and run at the low speed. My guess was a relay could have a problem. Any suggestions. I tried to read through the forums but couldn’t find an answer.
How does the depressed park wiper system work?
For depressed-park wiper systems, there is also some way to force the blades to return to the bottom of their travel, but notto go all the way into their fully parked position. The time setting between sweeps is controlled by a resistance value based on what the controls are set to by the driver.
Where can I get a delay wiper motor?
The switch I found on eBay, the wiper motor is available as a rebuilt unit at my local parts store, and the extra wiring harness can be found in a junkyard, or if need be, fabricated from scratch. The wiring diagram from the 1974 Buick Shop Manual is below, with the separate delay wiper harness indicated in red.
