Defogger problems of the 2002 Mitsubishi Galant

I bought the car, an 02 Mitsubishi Galant from a private owner who pointed out to me the knocking sound in the dash when switching from cold to hot air. A friend of mine has the same car and the same problem. Yesterday mine stopped knocking and blowing any hot air at all. It sounds online like many people has been mistreated by the dealership in regard to this matter. Now I don't know what to do, because I have to have at least defrost in my commuter car! please review this chronic problem with this model.

A/c heater blend motor worn out. Very expensive to repair, because the whole dashboard has to be ripped apart.

No heat. Went to niagara falls in the end of April 2005 and was stuck with no heat on a frigid rainy night. Due to the lack of heat, the windows could not be properly defogged and passenger compartment was dangerously cold. One occupant became ill (minor). While openning the windows a crack helped, the windshield still fogged. The windows could not be openned much due to the rain and cold. Luckily a napkin was available to wipe the windshield , otherwise we may have been unable to drive and stranded on a remote stretch of highway. The mileage was about 35,000 mi.

Clicking noise when turning the air from hot to cold or cold to hot. Clicking noise stopped and heat no longer works. I have no defrost/defog which causes problems with visibility. I am taking the car in for repairs this week. Paint faded and corroded on the hood, trunk, roof, quarter panels, and door panels in 2004. I took it to the dealership and was told they couldn't do anything about it. I have recently taken it to a body shop and had it repainted.

Mitsubishi Galant ES, has a problem with the heat/ac control, makes a grinding noise, it also locks into a position which only allows cold air to be vented. . . Bad if its cold outside. Mitsubishi wont replace the defected parts, they ask the customer to pay for parts and labor. The problem began while under warranty but was never replaced.
