I have an 04 Trailblazer and just had my battery replaced as well and a 125 amp fuse. The mechanic at the dealership told me we blew the fuse because when we jump started the suv, we crossed polarity. I told him we didn't but he wouldn't check the dash vent fuses without another labor charge so i am stuck with frozen feet and frosted windows for a few weeks! I was hoping to find an answer!The same problem happened to me when I replaced the battery. I too have an 03 Trailblazer. The AC works great through the defrost and the floor, but no vent! I'll keep looking for the answer. I hope someone posts the solution fast. It gets hot in Texas. Same here...'03 therr are two answeres to this problem posted on this site my best solution is to pay a dealer.
You need to replace the HVAC mode actuator. This is found under the dash. Trailvoy.com has additional details on how to replace this. Do a search in their forums. They have answers to almost anything dealing with Trailblazers and Envoys.
The battery in the remote needs to be replaced.
The best and fastest way to reset the instrument panel of 2004 Trailblazer is to disconnect both battery terminals. Reconnect them after about 30 minutes and everything should be reset.
make sure the small wire is hook to the post
The fuse for the cluster may have popped. Please realize that the 1999 Blazer is a totally different Platform from the 2002 + TrailBlazer/Envoy/Bravada/Rendezvous/Saab97X GMT360 pl;atform trucks.
disconnect the battery
Try an engine heater or an oil heater. These are both inexpensive.
Sounds like a pulley may be freezing up. Have a mechanic check the pulleys.
apparently you have a draw or a short when the vehicle is shut off, disconnect the battery when not in use and see if the battery stays charged.
This was caused by a poor connection at the Battery. We disconnected and and reconnected the new battery and everything worked fine.
When you change the battery you automatically reset the PCM. Any time you remove the negative battery cable for about 15-20 minutes you will reset the PCM. This will reset your Check engine light also. www.trailvoy.com Trailblazer enthusiasts forum with all the answers for your Trailblazer.
Check the starter, spark plugs, distributer cap, battery.

Your alternater might have to be replaced. Chances are your battery was not faulty. Your alternator most likely needs repairing or replacing.
Probably a weak battery.

Sounds like you have something that is on all the time and drawing power from the battery. Check, dome, courtesy, trunk, hood, glove box, and brake lights.
I'm sorry if this sounds silly, but did you put the battery in backwards?

Take your key and stick it into the lock on the door and turn.
You have a bad battery or you have a bad alternator.
