'01 7.3/engine jerks when wipers go on

[sierrasurfaces]

In wet weather while driving at mostly highway speed the wipers will cause the engine to jerk as soon as they start up.The strange thing is that it's not consistent. Has anyone had this problem ?

This is a new one on me!? I would check your body grounds and make sure there are no bare wires for the wiper circuit. Other than that i'm at a loss! Good luck and merry christmas!

Welcome to Powerstrokeforum.com Sierrasurfaces! I'm sorry I do not have any ideas to help you out with that problem. However many members will see your post within the next several hours and perhaps offer up an idea! Thank you for joining!

I get the same problem when I key up my CB, especially if the linear amp is on. I can't figure it out. Someone here will definately be able to help you on yours.

Hey over10rd. I wonder if your cb is sending out a frequency that is screwing up the ecm when you power up? I heard of things like this happening but i don't know how true they are so don't quote me on it.

Me too. My truck is doing the same thing. I had the wiring manual out all day to make sense of this. All checks out OK. The only thing I can come up with is the sensor is shielded and an induced voltage is affecting with the sensor operation. The wiper wires and the cam sensor wires are in the same harness. They do not share grounds. I am so glad it is not just me.

My truck will skip a beat when I open the drivers door. Go figure?

I need to replace the battery cables, so I hope it fixes the problem. May also want to check yours.

Thanks, but I don't open my doors at 70 mph! I will let you know.

Wellll... My opinion. Pull Every Darn Fuse in the Power Distrubution panel under the hood and clean them. I think the power to your PCM relay is dropping low when you turn the wipers on. I just got an expensive education on Fuse problems. My truck was running, turned it off and it wouldn't crank up again. Yes, I studied the wiring dia. also. That's how I figured out it had to be a relay or fuse problem (if the PCM hadn't died).

Derick, you are joking about replacing your battery cables? If your interior lights are maxing out the current your battery cables can carrie... It's not possible. Tighten the left rear lug nuts first and see if that helps or just don't open the doors.
