Need some help ASAP everyone!

Ok, here are the symptoms:
1. When in intermintent mode, the wipers go to the top then just stop, they never move after that.
2. Wipers work fine in low/high speed but when I turn them off, the don't return to the park position.
3. From inside the car, I can hear a clicking sound coming from under the dash near the ICU, not sure if this is normal or not.

What I have done:
1. Hooked up the wiper motor directly to the battery and everything worked fine.
2. Switched out the steering wheel control arm with a known working unit with the same problems.

Ok, so I am kind of stumped. I really don't want to swith out the ICU if I don't have to. Any suggestions or tests I can do to eliminate possible problems?

Thanks in advance everyone!!

 

Nobody??

 

Replace the ICU, intermittent wipers are controlled by the ICU. 94

 

That's what I figured, thanks!
