Easty $6 fix and very very common when the battery is unhooked. Unhook your battery again, and clean the throttle body, best method is to remove it. Use sensor safe cleaner, about $6 in a spray can and get it shiny clean. When finished, connect the battery back up and turn off all HVAC controls. Drive around for maybe 15 min and let the computer relearn the correct settings of a clean throttle body. When you hooked the battery back up the first time, computer thought the throttle body was clean, therefore sending mixed signals when every your defroster or A/C are turned.

Reset computer after battery change 03 trailblazer

Computer will reset after driving it around for a 15 min or so. Make sure your throttle body is clean, otherwise won't run correctly and possibly stall if your AC/Defroster is on. Cleaning it will solve this.

Need to reset the PCM on my 2003 Chevy Trailblazer .How do i do it?

Disconnect the NEGATIVE battery cable from the battery... Hold it or position to the POSITIVE battery cable for about 5 minutes. Also make sure you leave the key in the ON position (Do not have the engine running) and this will clear the memory on all computers/modules in the truck.

Why wont my 2005 chevy trailblazer run correctly after a battery change?

Because the computer was reset after battery change, and you probably need to have the throttle body cleaned. It grimes up often and needs to be cleaned every 10 - 15K miles.

Trailblazer 03 5 doors the door #5 is.locket unlocket??

If you recently unhooked the battery, that's your problem. Unhook your battery again and let it sit for about an hour. This will reset everything and should work again. You can also unlock it manually by removing the plastic cover on the door.

03 trailblazer 4.2 l code p0172 has no power

P0172 02 sensor is detecting that the system is running too rich. An 02 sensor that is starting to go out will pull this code, but the following will cause the 02 sensor to throw this code as well:

A few things to look at. 1st thing I'd do is clean your throttle body with the battery disconnected. Use sensor safe throttle body cleaner, about $4.

From there, I'd look at your upstream 02 sensor, located on the exhaust manifold on passenger side of engine, very easy. Try and stay away from Bosch if possible.

New fuel filter, clean or replace your MAF sensor located on top of engine next to firewall. Also, probably time to change your spark plugs. I recommend A/C Delco 41-103, will idle better than other brands.

My battery dies overnight on my 03 trailblazer, i can jumpstart it and runs fine and i shut it off and start back up and it runs, but when i leave it off overnight the battery dies down again.

Check all your connections at battery to make sure they are tight, and clean, but my guess is it will probably need to be replaced, unless you have a large current draw happening. Stop in to an Autoparts supplier, or your preferred repair shop and ask them to test your system, as in battery , and ask them to double check that there isn't a large draw when engine is shut off. Sounds like alternator is o.k. as it is charging battery, but battery isn't holding charge, and a quick test by knowledgeable technician will confirm whether it's battery, or something drawing it down. If you happen to have another good battery you can try for a day or 2, that will also tell you.

Battery goes dead every few weeks..I recharge it and it will stay charged for a few weeks or months. Then goes dead again.

I just recently had the same issue.  Have someone check all the fuses and see what is drawing the power down.   Do you have electrical seats?  OnStar? Also have someone check your ingnition to see if it is fully turning off.  Trailblazers are supposed to have the 'run down protection' but something that drains your battery little by little could be the problem.  It seems that trailblazers need a lot of juice just to get started...
