Air Vent problem w/ 1994 3.4

[jpmurphyslaw]

Here's my problem...

My Camaro won't blow air through the vents, she will only blow air throught the floor and defrost.

I assume this is a vacuum line problem.

Anyone know where to begin looking? Any particular place that causes trouble? I notice that behind the A/C controls there are several different color coded wires/lines. Are these in fact vacuum lines and do I need to replace them?

Any help is greatly appreciated.

thanks,
Philip

more likely than not its an actuator problem, rather than a vacume problem. i dont have a service manual handy, but the dealership should be able to diagnose it pretty easily

So as I was traveling down the road the other day... she begins to blow air through the front vent.

Turned the car off and started it up on the way home... blew out of the defrost.

Came in to work... blew through the front vent.

Still think it's an actuator problem?

thanks.

to be honest, now it sounds like a head unit problem.

yeah i think you might need a new logicon...
