for months i have been smelling an odor coming in my vents that made me ill. i took it to a mechanic near where i live. we thought it was a gas leak, he didn't see one so told me to just drive it until it gets worse. i wasn't satisfied with that and since i am new to this area, i don't know anybody to ask for references, i decided to take it to AAA. they found the problem and repaired it. i don't care about the fees, as long as they are 100% trustworthy, reliable and guarantee their work. i do have to take it back to get gaskets replaced and i will, but my ac works great, the smell is gone, i feel safe in my car again.
