Hi all, I am new to this forum and would like to ask if anyone can help with the following problem: My early 2009 Outback heater vents emits slightly warmish air even though the outside air is much cooler. The Set Temp. is set to 18 Deg. C. Everything else works fine, and when I switch on the AC, I get good cold air. It is if the heater water tap is leaking hot water, but I am suspecting that these cars do not have a conventional heater water tap? I could probably fix this if I new where to start. Thanks to anyone who can help.
