Problems with windshield wipers..

With the multi-function switch in the OFF position; wipers run on low
speed. Will not shut off at all. Have to turn ignition off to stop
wipers. Wipers will stop at any point on the windshield when ignition is
turned off. Have to have pulled the fuse to stop wipers when driving.

With the multi-function switch in the INTERMITTENT position; wipers run
on low speed.

With the multi-function switch in the HIGH position; wipers run on high
speed.

Mist mode works fine.

Pulling back on the wiper control lever to initiate the spray works fine.

Sound like the ICU is bad ?
