We recently took our '05 Matrix to the dealer for it's 20k class A service. As usual, my wife received a mid afternoon phone call from the service department saying that they found something else that needed to be done. Apparently they found some debris in the AC system that could potentially lead to a clogging of the A/C drain and recommeded a "evaporator system fush" for $130. Our A/C was working fine and draining properly prior to the service. She hesitantly agreed to have the service performed, not knowing what they were talking about. I feel like we were taken for a ride. Our car is only a year old, we don't park outside so we don't have a bunch leaves, etc falling on our car to clog up the vents and I personally have never my A/C drain clog on any car. Can anyone give me a better explanation of why I would need an evaporator system flush and is there a way for me to do this myself? I have a hard time believing that all of a sudden I need to spend $130/yr to flush something I've never had a problem with.
Thanks
