I have been driving for a couple of years with a broken ac/heater in a 2009 Saturn. About 3 weeks ago on a warm day, hot air started coming out of the vents even while the knobs were in the off position. The vents were hot to the touch. After a relative of mine had Birdsong fix engine issues on their car, which was older than my car. I decided to see what they could do for my car. They took on the challenge of finding parts for the 2009 Saturn, which I'm sure wasn't easy. The ac/heater is working wonderfully now, and with summer just around the corner, not a moment too soon! I will continue to take my car to Birdsong Automotive for future repairs or as long as they can find parts. I would HIGHLY recommend them!
