Re: [doc] Re: Heater - aircon -slightly OT

[Martin Gutkowski <webmaster@xxxxxxxxxxxxxx>]

AC equipped cars often come with a "recycle" switch which closes off the 
intake from the outside air. On my Xantia, it's a seperate control, and 
if you forget and leave it on recycle and turn the ac off, you mist up v 
quickly. You also get the "damp earth" smell. The DeLorean only closes 
off the outside air when you switch it to "max"  - this is the only 
difference between Max and Norm. On other cars, I'm guessing the recycle 
bit may be inadvertantly left on more easily.

My old BX used to keep a low breeze blowing over the windscreen on 
whatever setting on the dial - very useful because it never misted up 
except when stone cold. It did not have a recycle option.

Only late DeLoreans, and those with late style mode switches (like 
John's) will fire up the compressor when on demist. As to your specific 
problem, John, I have not seen this problem before but would guess one 
of your vent flaps isn't doing what it should - my car blows strongly on 
"heat" as on AC.

crisis. Ac still works a treat after 105,000 miles
