Got a 2004 Acura TSX. Air conditioner compressor locked up. Mechanic replaced it. 14 months later the compressor blew up. Replaced it again under warranty. I asked the mechanic if it is the condenser unit being clogged the caused the problem and he said it is not clogged. I was wondering should I take it to another mechanic to get the condenser unit replaced. The AC unit seems nice and cold but I realize a drop in MPG.
