You could have a damaged battery cable. They can get corroded and act like a dirty terminal. Make sure your connections are really tight also. Try to "wiggle" your battery cables. Have the battery checked also.
usuallyyou just disconnect the battery terminals for about 3 minutes.
Just disconnect the battery terminals for a couple of minutes then reconnect them.
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.
remove the battery terminals for a minimum of 10 minutes.
Remove the positive terminal on the battery for 20-30 minutes and then replace the terminal on the battery and tighten the bolt very well. Also, for battery acid build-up on the terminals, pour several cups of boiling water over the battery terminals.
disconnnect battery termials, wait 10 minutes, touch the terminals together, reconnect
Take the terminals off the battery and leave them off for 30 minutes, then put them back on.
It is going to be one of a few things. First thing to check is the battery terminals. Look for loose or corroded terminals at the battery. If after cleaning them with a wire battery terminal cleaner brush, and tightening them it still will not start, have the battery checked to see if it is good. If the battery is good, then have the starter checked.
Unhook the battery for ten minutes.
Try unhooking both battery terminals +- for a few minutes, that should reset the system.
i think what it is, you need to charge your battery but let it charge for about five minutes and if that doesn't work then you need a different battery
When jumping a vehicle with a bad or totally dead battery, it is best to connect the two vehicles and let them sit for about 10 or 15 minutes with the "good" vehicle running before attempting to start the "bad" vehicle. This allows the dead battery a chance to build a charge so that the jump doesn't try to pull so much current from the good battery (which is already providing current to keep its own car running). Be patient and WAIT AT LEAST 15 MINUTES! Don't try starting the car every couple of minutes or you will drain the battery again and the 15 minutes starts all over. You also might want to replace to battery terminals on the battery cables. Most likely the stock terminals are made of lead and are subject to corrosion. You can get a great set of brass terminals from an auto parts store for about $5. They are really easy to replace -- snip the old ones off with about a half inch of cable (which has corroded with the terminal), strip an inch of insulation to expose the new cable, and bolt the new terminals on nice and tight.
