PT Cruiser air conditioning question

Air intake is outside in front of the windshield, the cowl!! If you always have your a/c on recirculate it will tend to have a musty smell, especially if your a smoker Glenn Beasley Chrysler Tech

Thanks for the instant response! I'm not a smoker, and I never use the a/c on recirculate, but the smell has started to appear in the last few months. I guess it is due to bacterial/fungus growth in the system.

I read somewhere that you should always turn the air-conditioning off a few minutes before the end of your journey to avoid this problem, but I have absolutely no idea whether there's any truth in it.

Yes I read that, too, but it doesn't seem to have worked. On the other hand, every other car I've owned with air conditioning has developed the smell, so I guess it is to be expected eventually.

What they mean is turn your heater on before you shut the engine off, this will remove any moisture in the system and stop bacteria growth. I just find it hard to turn the heater back on in a very hot humid day just after I cooled down with the A/C

Yeah - turning heat on on a hot day at the end of a drive for the privilege of using the air conditioners is one of those paradoxes of modern life. Another one is sitting for an extra minute at idle after driving your turbocharged vehicle (you paid extra money for turbocharging so you could get there faster, right?). 8^)
