Defogger problems of the 1998 Plymouth Breeze

Oil leaking from head gasket, was discovered during inspection of shifter cable which wasnt installed properly after replacement due to a recall. The extended warranty had ran out the day before it was noticed, although it had apparently been leaking for awhile. Cruise control quit working, when you depress the button to turn it on, the light comes on but the speed cannot be set and after a few tries the light will go out and you cannot get it to come back on. A/c vents, there is a strange smell that smells like mildew or mold that comes from the vents when you turn on the air conditioner or heat, this has been adressed with a dealership and was taken care of but returned a few days later.
