Here is a thread on a tool to help with the wipers. They can rust pretty solid. PB blaster and tap on the spindles if you can, that will help it soak in. Make up the tool if you are handy, I just slip a piece of rubber hose over the spindle and fill the tube with oil and let it soak in overnight, in your case fill it up with penetrant. Also I have seen the outer bushing start turning and the inner shaft still seized and the wipers will work but it is still seized, not good. I would put in my vote for the real cool clear plastic heater levers. They look great all lit up at night. Your heater operating cables are probably siezed and your linkage from the drivers side heater flap to the heater core water valve is more than likely not working. Be very careful here as you can break the lever on the heater flap, an expensive fix, or epoxy it. The heater motor also should be cleaned and some light machine oil worked into the shaft where it goes into the electric motor if you get it out. I could go on and on, but this has all been posted, search and ye shall find.
