Ok ... I searched the faq's and the tech sections and the owner's manual I just bought and I can't seem to find a way to turn on a fresh air vent. How do you get outside air to blow through the dash? I have the AC working great now and got the heater to turn off by replacing the valve but it would be nice on some days to have just cool fresh air without opening the window. What am I missing??

TIA
Glenn

Hmm... this is covered in the owner's manual

OK, top left lever all the way to the right. Top right lever all the way to the left (the levers should be together) and the bottom lever all the way to the left.

BTW, this is also the correct A/C position. Thus, for warm weather driving, the levers should always be in these positions.

Oh, and make certain the dash vents are open

I always find it funny how many people can't seem to work the levers right. The guy I bought my car from said he never figured them out in the 2 years he'd owned the car. After about 20-30 secs of looking at the pictures and fiddling I learned how to use them perfectly. If the pictures were worn of or something then yea it'd be a pain to figure them out

Guess I didn't word that well

I had no trouble figuring out what the levers were meant to do except for the outside air part. My owner's manual sez that the lower control all the way to the left gets outside air. But I don't get outside air in that position. I have all the levers set to A/C mode (top 2 centered bottom one all the way left) But unless I turn on the fan I get no air from the vents going down the road. Is this the way it works or is there a flapper someplace that isn't flapping??

Thanks Again
Glenn

are you sure that the center vents are open? The little knob/lever thing on the side of the vent should be down.

As for learning the heater controls, ill be honest im still not 100% sure about them even after reading the manual. If i want heat/cold air to come out of the floor vents, what position do i need to have the levers in? The top left lever to the left, and the top right to the right correct?

This is really a lot easier than it seems.

The top left lever controls whether the air comes out at the floor vents or the dash vents (left floor, right dash).

The top right lever controls the defrost (right position blows out of the windshield vents, left position closes those vents).

The bottom lever controls cold (left) or hot (right).

The A/C position was described in my previous message above. The heat positions would depend on where you wanted the heat directed.

In addition, closing the side vents will direct hot air to the power mirrors.

Hope this helps

Ok ... that all makes sense now. Thanks much.
But ... does it blow fresh air just from going down the road with the upper levers to the middle and the lower lever to the left? Or do I just need to be happy with opening the window

That is what it took to fix that condition on mine. Getting to the valve is not easy but they are cheap. Something like $14 for it cause they use the same valve on VW's or Audi or some such thing. Hint ... get a LOOONG extension for a 1/4 drive to get to the hose clamps I used about 20" of extension to get to it so I could run the clamp while somebody else ran the wrench. It is hidden between the motor and firewall under a bunch of connections etc.

Bingo!! That is the info I was searching for

Thank You! Now I just need to figure out what isn't opening. The vents are open in the dash as either the heater or the A/C blower blow through the dash vents. I just don't get any outside air through them going down the road. Must be something to do with the bottom lever. I know it operates the heater valve and that works now that I replaced it. Guess I will pull the heater controls again and see what else is hooked to that lever.
Thanks for all the help and sorry I had so much trouble asking the right question
