air con stale smell

Hello Dingo,
Make sure the condensate drain is clear. Often they collect a leaf etc. then the water will collect and smell.
Haven't got a wet floor too? Usually a good sign of a blocked drain.
It'll be a rubber tube, 12 to 16 mm diameter open ended and hanging through the floor pan or firewall somewhere about the bell housing.

Best place to start for A/C smells.

you or previous owner a smoker?...
try running the aircon so that it makes ice and freezes then defrost the coil do this many times to rinse the coil of stubborn odours.....never tried it my self but the idea sounds as though it should work

there is a coil cleaner available from refrigeration wholesalers but the problem is getting to the coil to spray it on...

There was a good post some time ago about cigerette smell in the air con unit , I have searched under all sorts of names etc put cant find the post , any one remember when or did a reply on the subject.

Cheers

You can take it to Toyota dealer and for about $40 they will put a deodouriser in the system. Works well.
Cheers Peter

Or buy a glen 20 pressurepac and with fan running, spray it into the inlet.
