#1. Is the car warmed up? (I know it's obvious but still)#2. The trim piece on the T-bar that has the map lights on it. Take that off and see if the little fan up there is spinning#3. Heater core...

All i can think of.

Also, another note on the little fan in the roof (climate control cabin temperature sensor) if the two sensor "wires?" are touching, that will register 0 resistance across the pentiometer, making it think that it is 9 billion degrees in the cabin, so the CC will try to compensate and blow cold air. Opposite is if a wire is broken, max resistance, all you get is heat.

The trim piece is easy. Just carefully pull it from the sides and it'll pop off. Just let it hang.

Could also be the motor that operated the mode door that directs the air through the heater core or not.

Have you tried running diagnostics? I assume you have the climate control

I could never figure out how to use that friggin thing....

I got it into diagnostic mode, but couldn't figure anything out from there.

check your antifreeze to see if its low. You won't get heat if it is. See if the temp gauge is not where it usually is. The car will start to run alittle hot when its low on antifreeze.

Most likely, heater core. Had this issue with my previous Z, having it again with my new Z.. tons of fun. Never replaced them though I will with this one. Entire dash must come out, supposedly a 10-15 hour job.

I feel your pain.

You can use this guide: http://twinturbo.net/net/viewm...01202 if you don't want to tear the dash down. I haven't used it yet but a friend of mine said it was easier (in some ways) to use this method. If you'd like to tear the dash down however you can use this guide: http://www.twinturbo.net/net/v...68248 I haven't decided which route I'm gonna go yet..
