On my 05 3500, wipers sometimes cycle 4 times before stopping when on intermitent? Sometimes will not turn on unless switched to WOT speed. Slow and High speed seem to work its just the intermitent. Anyone know whats up?

 

the wiper assembly on the steering column could be bad or have come somewhat unplugged. same with the wiper motor. id check those first. if not those a wire could be shorted or a ground could be bad not allowing proper connection between the two

 

Before you do anything check the relay for the wiper. I just fixed the same issue on my 05 and replaced the motor before I figured out it was a 20$ relay.

 

I've had this happen and it was the multi-function switch. I've actually had this switch replaced 5 times because every 1 - 1.5 years it goes bad (turn signals, wipers, etc.). Last several times it has been out of warranty but a friendly call to Dodge and they agreed to cover the bill.

 

There is a recall on the 06 mutifunction switch. Do a search on here and you might find it...

 

Just recently started having a similar problem on mine. I'll have to check the recall/tsb notices.
