Ok I don't know if this is the right section but here I go anyway.

Ok I have heat but it doesn't blow thru the vents? Same with ac, nothing thru the vent?

I checked the HVAC fuse and pulled then blower motor and both are good but I get nothing thru the vents what's up with that?

This is on a 2000 trans am by the way.

Any help would be appreciated

Hi, check your "vacuum blend" located behind controls -underneath radio. This operates the doors to allow air thru vents/floor/defrost. You also have a resistor located on passenger side underneath hvac box. This controls high speed fan. Can be a little tricky to locate but has only one screw holding it in place.

Way to hijack a thread there buddy. Anyways, OP, defrost position is the default position if there is no vacuum supply, so I would takevthe second posters advice and pull your control panel and ensure you have vacuum at the mode selector.

To the hijacker... Get a test light and start testing for power at the fan, the blower resistor, then the fuse. Find out where it all goes "bye bye power."
