Get the parts from RockAuto... much, much cheaper than the dealer, even Motorcraft branded parts there are cheaper there as well. All of the brands they stock are good ones, so all you really gotta do is find what you need, and pick what you prefer.
The connector won't come apart easily because the terminals are rusted together... mine was melted badly as well. It took a lot to get that thing disconnected.
What I did is seal the back of the new connector with RTV to keep **** from getting into there... one place where a GM Weathertight connector would be very beneficial, as it is pointing the back of the connector towards the front of the truck, open to receive water, dirt, and crap like that. Unfortunately, they gave us the open back connector...
As for the wipers, I have a weird issue with them as well... when they are switched on, they will wipe consistently for a bit, then not wipe at all for a little bit. (not talking about the delay... it'll go wipe, pause, wipe, pause, wipe, pause, pause, pause, wipe, pause, wipe...)
It'll do it unless you have it on the full speed 'wipe the hell outta the windshield' settings. Also, the wiper arms are a little loose. Gotta tighten that up.
Well folks, out I go to fix that exhaust leak behind the cats, and inspect them as well. If they are starting to plug up or are plugged, off they come... (gotta love Michigan!)
