2005 LS hatchback we purchased used with this problem. The intermittent setting doesn't work and the wipers won't park. They stop whereever they are when you turn off the switch.

They operate on low and high just fine and the rotary switch on the motor operates perfectly, I have examined the contacts and metered the pins on the wiring harness with the wipers in both parked and operating positions and the switch is working.

I cannot see anything wrong with the switch on the steering column, contacts are moving properly and not burned or corroded etc.

I think I should be hearing a relay click when the wiper is on intermittent, but there is no noise inside the car when switching the wipers on and off other than the noise the switch on the column makes.

So, I am looking for the wiper relay. Anyone know which one it is?
