Hey, I just bought a 2004 Neon with a problem.
When the car is not running I can turn the ignition switch to "on" and the wipers work normally, on, off, delay...
If I start the engine, wipers run all the time and will not turn off.
Get this...
If I step on the brake the wipers stop. If I let go the brake the wipers start going again.
Does anyone have any idea what could be causing this?
I have tryed 2 other multifunction switches and same thing. I have switched the wiper motor, same thing.
Is there a relay in this circuit? If so, where is it?
Thanks much, Mike

 

Mike what was the resolution of the wiper issue???

 

Ok since Mike dosnt seem to be on here much and I needed to get my Daughters car finished I had to diagnose the answer myself (no shortcuts)
The answer is... a bad (shorted)washer pump motor and multi function switch(stuck on wash).
I got ahold of a wiring diag and started pining things out and found power going to the washer pump (at the switch) but the pump was not running, so I unplugged the pump and voila...issue gone. The stalk wasn't in the wash position so it must be stuck/shorted.

 

Sorry for the delay, computer issues...


That was the solution for me too. I unplugged the windshield washer pump and everything worked fine after that. I just left it unplugged.
