Re: 2002 Trailblazer is only blowing AC through defrost and floor
That is usually a default position caused by loss of vacuum...

Pretty sure the modes are electronically controlled on this one. Did they work normally before the battery was replaced? If so, you may try disconnecting the battery and holding the positive and negative cable ends together for 30 sec or so. This will deplete all capacitors in the car and reset all modules. Then reconnect the battery and see what happens. |

Re: 2002 Trailblazer is only blowing AC through defrost and floor
MY BAD.....GMTech1 is correct....you have electrical actuators, not vacuum.....all actuators have a common fuse, HVAC fuse, #39, 10 amp, located in the rear fuse block...
