I have a 2003 trailblazer ext my a/c works when it feels like it. The fan blows at every setting, but no cold air is entering the vehicle. My a/c system is charged. To me it seems like the a/c clutch is not engaging. I have had this problem since 2003, have asked the dealer about a possible recall. The have said that the system is fine. Has anyone had
this same problem? Any solutions?

On my '03, there are two push buttons under the radio volume knob. One marked H and one marked M. Press and hold H to change hours, M for minutes. Need to hold for 5-10 seconds before anything happens.

2005 trailblazer has excessive air leaks around doors. dealer claims this is normal and after 2 attempts to resolve this problem stated this is a design problem and can not be corrected.I have ridden in other trailblazers and I did not notice this problem.
On a windy day or in the winter the wind whistles through the windows, mine is a 2005 as well. People have put visors above windows, they claim they work.

Look at the radio panel, to the left of the chanel buttons, there are two little buttons. You need to press and hold each to set the hour and minutes. AM/PM switches by passing 12 hrs, rather then by pressing some other buttons on the console.

Not sure what the issue is, but we are having the same exact problem. We had to replace the batter in ours in August and the vents no longer blow air from the dash, but all of the rest work. I have seen SEVERAL complaints like this online, but no solution. I have even seen where people have spent a lot of $ to have the problem fixed and it still doesn't work. Hopefully we will figure this out soon.

I have a 2003 trailblazer with 70,000 miles on it and it kind of looks like the battery light is on but not very bright I have checked the battery and alternator and both are good.so why does it look like the battery light is on(dim)as if a light is on behind it and making it look like it is lited up?

Not sure if you've already found this out, but make sure your radio is off. There are two, very small black buttons at the bottom of the radio face plate. Hold the left one down until you hear it beep and you will see that your clock is blinking. Use these two buttons to set the time. Then once it is set, leave it alone for a few secs and it should stay.

I have an '03 lT Trailblazer EXT with the indash CD changer. The radio works fine but the CD changer thinks that there are two CDs in when there aren't any in. When I press the 'eject' button, it makes noises like its trying to eject a CD but then give 'PLAYER ERROR' message. Anyone know of a way to reset the darned CD changer?

I am having the exact same problem, dealer wants $60.00 + to change it, the manual does not have the information either.
Just changed the passenger side low beam on my 2003 Trailblazer. No need, repeat no need, to remove the entire grill. Just need to:
1) remove the air filter cover
2) reach behind and remove the rubber boot
3) twist the bulb 1/4 turn and disconnect from wiring harness.
Save yourself $60.00; takes 10 minutes.
