So I have a weird issue. It happens 99% of the times when starting my truck. When I start my truck, the wiper goes across once and then stays down. Why does it do this? It's so annoying....

 

Waving Hi to you?

 

LOL its not funny, its annoying....

 

bump....

 

I had this issue a couple days back when it was raining. If I turned the wipers off and shut the truck off it would go once when I started it, or actually just gave power with the ignition really.

I decided to cycle them off, on, then off, and then turn off my Dakota. It didn't go back when I started the truck.

I used the wipers quite a bit the next day and had no issues, though I *did* changed wipers the day it was sleeting. Perhaps wiggling the motor as I took old blades off new ones on fixed it instead? I hope it isn't coming back, odd issue indeed.

 

CTSNicholas,

The windshield wiper module is controlled by the battery currents received by the wiper motor. In some cases, if the wipers are functioning in an erratic fashion, a loose connection or wiring issue may exist.

@Jeremysp1993, I'm sorry to hear about you wiper issue. If the issue occurs on every start-up, a communication issue may be present in the wiper module.

 

Have your alternator tested. Had this issue with the wipers on a Ford awhile back, and it turned out the alternator was on its way out.
