Well I spent quite a bit of time on the heater controls and came up with no easy way to shut the water valve off. [I just can't push it closed with the cable in the housing]. I did learn how to put my hand in behind the heater and move the valve a bit, so that's my fix.
While I was lying in the cab pondering, I decided to put a drain hose from the windshield housing down through the floor, behind the kick panel. NOT easy, but it's done. Every time I washed the truck water would sneak in past the windshield gasket and run down onto the cardboard kick panel and warp it more.
Sometimes when I was going on the highway into a rainstorm the wind would blow my windshield wipers up off the windshield and onto the roof, well then you just have to stop and get out in the storm and bring the wipers back down. Oh ya, then you're all wet and not a happy camper, especially when you get up to speed and the wind does that to your wipers again. So,,, I made a stopper on the windshield frame to stop the wipers going crazy.
Then, we snuck away to Puerto Vallarta for a week, so no fixing was done.
