I've got the same thing. Low and high work, but between is total hit or miss.

 

It's just hit and miss but it seems that the slowest setting is the one that works the most no matter were I have the switch set in the intermitted range.

The interval governor is not part of the motor, the park governor is.

 

My wipers don't have intermittent and they don't park
benches Hi and Lo are fine and anything to left of off is constant low no matter what.

Point is with no parking, should motor be replaced for that to be fixed?

 

Where is the interval governor?

 

On '94, somewhere on the passenger side behind the glove box.

 

Perfect thanks

 

Thats right sorry, i was thinking they were built into the same unit. But this should show you where to look, on the RH side behind the lower glovebox are next to the ABS module

 

OK I’ve finely got around to crawling in and looking for the wiper control module. Looks easy to find but not sure how to remove it, dose anyone have a picture to make sure I looking at the right thing and dose anyone have any experience removing one of these?

 

No one here has ever changed out one of these?
