There appears to be a heavy current draw on the battery, you need to monitor this current draw with an ammeter and then start pulling fuses until the current draw is reduced. This will lead you to the circuit, then you will need to determine the cause in that circuit. This task maybe best for a qualified car electrical technician.

Rear ac blows in my 2004 Chevy trailblazer when vehicle is off. Front ac is off. What could be the problem? Just started after changed coil pack and hooked battery back up.


Turn everything, all switches, off then disconnect both battery cables and leave disconnected for 30 minutes. This resets PCM to defaults. Then reconnect ( + ) first then ( - ).

After using your A/C and you shut vehicle off in your garage or drive way see if it leaks water on the floor or ground. If it doesn't your evaporator drain is plugged. Not uncommon to see this.

Oil drain plug size on a 2002 chevy trailblazer


If your going to work on your own vehicles, you need a basic set of tools, wrenches and sockets, standard and metric sizes. Generally it's cheaper to buy a set.

I'm thinking 15mm,but, I could be wrong.

Battery light on my 2004 chevy trailblazer. It lasted a day then all the ABS breake light came on the the battery drained. The truck shut off. What could this be. I bought a brnad new battery 2 years ago.


The battery light comes on when there is an issue with the charging system. Most likley you have a bad alternator. With the engine running you should see a min. of 13.5 volts at the battery and better yet 14+ volts. If you have 12.5 or less than the alternator is not charging.

Once the vehicle is started the battery is no longer in play. The alternator is what keeps the power supply to the vehicle and recharges the battery for the next time you want to start the vehicle. Once battery voltage drops below 9 volts or so systems start to shut down. Eventually the battery will drain enough that the engine management system can no longer function and the vehicle will stall.

I have a brand new battery, alternator, and cam shaft sensor on a 2002 trailblazer. The vehicle requires a jump daily and if the vehicle is running, and I turn the a/c on, the motor will stall and then...


Check for unwanted current draw. Disconnect the negative battery cable and connect a high impedance test light between the cable and the negative battery terminal. If the light comes on with everything off then something is continuing to draw power. Remove the fuses one at a time until the light goes out. Look at the fuse cover or the owners manual to determine what the last fuse that was removed is used for. Something on that circuit is shorted and needs repaired or replaced.
