I've been having problems with my AC. Whenever I turn my AC on when the car is idling the alternator charge drops from between the M and the A of normal to the O and R. Along with that the AC puts out a weird smell. It kind of smells like maybe somethings burnt or some type of fluid. This only happens when stopped or when going slower than 10mph or so and whenever I get going 30mph or 35mph the smell goes away. Any ideas as I am stumped.
