intermittent wipers are not working on 2008 Subaru Impreza

I have 2008 Subaru Impreza and my intermittent wipers are not working. The wipers also do not return all the way down when turned off but stay in the middle of the windshield. The Hi and Lo speeds are working fine. I had a problem with the nut for the driver side wiper arm being loose. I tightened the nut and the wiper works. After I fixed the loose nut problem I started having problems with intermittent mode. Since we are having lots of snow having wipers work would be very nice. Your advice greatly appreciated.

You probably have a problem in the parking switch in the wiper motor. You could have bad connections, too, so check those things out.

How do I check parking switch and bad connections?

The wiper park switch is inside the wiper motor. Swap the wiper motor with one that you know works. If the problem goes away, the motor is bad. It could also be that the wiper arm on the side that had the loose not is positioned incorrectly and not allowing the motor to reach the park position. Remove that arm completely and try the wipers again. If it works, leave the key on, turn off the wipers to allow them to park, then reinstall the arm.
