This is a GM CAR.... The Circuit Board on the Wiper Motor is BAD...

Replace the Circuit Board and your Problems will be gone

For the Honda civic 2006, a 24 inch windshield wiper is needed for the passenger side and 28 inch windshield is needed for the driver side.------------------------------------------------------------------------

Windshield Wipers Not Working - Things to Check
To troubleshoot car windshield wiper problems, you need to thoroughly investigate problems with any of its operating parts. Here are some of the things that you need to check to determine why are your car windshield wipers not working.
Check Wiper Motor
The wiper motor is the driving force of the windshield wiper. Feel the motor and listen to a humming sound. If there is no humming, the motor is the problem. Check if the motor is working properly and see to it that its electrical connections are made properly. If you find that the motor is dead and beyond repair, get it replaced immediately.
Check For Break in Connecting Wires
The connecting wires of the motor sometimes go loose and that may cause the windshield wipers to stop working. Also check the battery plug connection which the motor has. Connecting the loose wires properly or fixing/replacing the plug might solve your problem.
Check Wiper Switch
Another wiper assembly part that can malfunction is the wiper switch itself. Check for switch malfunction and if you find that is indeed the problem, get it replaced from a mechanic.
Check for Bent Wiper Arms
Bent wiper arms can cause the operation of the wipers to be hampered. If the wiper arms are bent beyond repair, get them replaced immediately.
Check For Blown Out Car Fuse
A blown up car fuse could be the culprit that has stopped the windshield wipers from working. Check the fuse assembly under the dashboard of the car. Replacing a blown fuse might fix the problem of windshield wipers not working.
Windshield Wiper Sprayers Not Working - Things to Check
Sometimes the windshield wiper sprayer stops working which can be very annoying. The washer mechanism is a self cleaning mechanism for the windshield. Here are some of the things that you need to check in case it is not working.
Check Windshield Washer Motor
The windshield washer mechanism might have been impaired due to the malfunctioning of the wiper washer motor. Check if its working and get it replaced if it is beyond repair.
Check Windshield Washer Fluid Level
Sometimes the washer doesn't work because the washer fluid levels are not filled to requisite levels. Filling in fluid might restore normal functioning.
Check For Broken Washer Hose
The connecting washer hose that connects the reservoir to the nozzle, might be broken or worn out stalling the overall operation. Check the hose for leaks and get it replaced.
Check Washer Nozzle For Clogging
Last thing to check is the nozzle of the washer for clogging. An obstruction in the washer nozzle might be the reason for windshield wiper sprayers not working. Using a pin, clean the clogged nozzle. This might restore the sprayer to the normal working condition.

Could be anything but based on experience the probability points to the self cancelling switching in the motor gearbox.
