This is very important, i have been trying to sell my car and it has been sitting in my garage for like 3 months. I start it 3 times a week a drive it once a week to keep every thing running alright. The engine runs perfect, but i just went down into my garage tonight to start it and everything seemed normal, that is untill i turned on my ac. After a couple of minutes it started to smoke, on the right side of my car where the ac compressor is???? What could this be??? The only thing i can think of is the coolant is leaking somewhere??? Please respond asap! Thanks!
