2004 Honda Pilot turn signals / interval wipers

Hi----
About a week ago I started having problems with my LEFT Turn Signal and Interval Wipers.

Here is what is happening.
1. When I have the headlights ON the LEFT turn signal (only) blinks really, really fast. I have already changed the bulb and that has not solved the problem.

2. When I try to use the Interval Wipers they go half way up, stop, go all the way over, stop, come back half way, stop, then go down. They are really, really slow (even on the fastest speed). The regular, constant speed wipers work just fine, though.

I'm afraid that it is going to be some kind of eleictrical issue and the dealership is going to charge me alot to diagnose and fix. I would like to figure this out myself and then take to them if I need some extra work done.

Thank you!
