wiper control module
Mine did exactly the same thing... clicking near the glovebox, some of the intermittent settings wouldn't work, etc. Anyway, you need to change your MFS (turn signal switch). I did last weekend and it's perfect now. Advance has them for sixty bucks and all you need is to unscrew 3 phillips in the belly of the steering column molding and 2 T20 torx screws that hold the switch on. Unplug the two plugs and put the new one in. 30 minutes and I guarantee this will fix it. The guy at Advance will probably mention how many he sells, too.
