peugeot 406 - smell from aircon

May 06, 2004 4 Replies

The aircon works fine...nice and cool etc., but when I switch it off, a nasty 'cigarette ash' type smell comes through the heating vents. Its OK whilst the a/c is running. Can anybody help.



Might be fungus or so. Visit your dealer to have the system cleaned.

It could be mould or fungus growing inside the system - nice - you can buy special spray to clean it, or take it to the dealership.

It's worth deliberately drying out the system after using it - crank down the windows, turn the system off and select full heat for a couple of miles (when you get back home is useful).

Have just seen this and the 'fix' on another website - you have bacteria/fungus - you'll need antibacterial spray on all your A/C routings and filters - 2 or 3 times seems to be recommended - good luck!
