Heater door repair is VERY common--the heat and ac will get crazy--the doors break at the hinge--Mopar has a parts kit to fix for under $300 but labor includes R&R of entire dash, steeing column etc--lots of Mopar techs do this repair on the side--away from the dealership --power window motors will go bad --good news is that there are aftermarket ones now for cheap like $70---power steering hose has an odd connection end and they usually need to be replaced at least once-My wife LOVES her 2001--we have a 4.7 that will fly and always delivers 20 plus MPG- Good Luck!
