2000 Chevy Tracker A Funny Smell Coming Through Inside Vent

Every so often for the past 4+ months, there has been a strange smell coming through the inside vents of my car. It smells like a hair perm solution, believe it or not! My father immediately suspected that it is an antifreeze smell, but when I smelled a container of antifreeze, I can't say it smalled like that. I'm having difficulty with my air conditioner and coincidentally, it's been going on for as long as the smell.

Also, when I went to various auto parts stores, I cannot find the proper air conditioning kit to put freon in. The port on my car is the opposite of what the universal one sold in the store connects to; the store clerk, who seemed very knowledgeable, came out to my car and couldn't believe that it's the opposite as it should be! "Suzuki engine!" My dear father stated!
