Hot weather often causes weak batteries to die. Try a jump start and go to AutoZone for a battery and charger test.

Change your blower motor resistor,it's located next to the blower motor.

There is an electrical short in the system. Have it checked by a professional.

Check the connecter of you battery. There's a good chance your battery connecters are loose, or another problem with your battery connecters.

Most likely you have something draining the battery. Quick way to tell, disconnect the ground (negative) cable to the battery, let it sit for a few hours, then reconnect it and try to start it. If it starts OK, you know the battery is holding a charge, but something is draining it.
To drain it in just a few hours requires a serious draw, like headlights or the cooling fan. It is possible that your cooling fan (behind the radiator) is staying on all the time. Often they are controlled by a thermostat, and will run for a few minutes after you shut off the engine, but it should shut off within about five minutes. If it is still running after ten or more minutes, you have a bad fan thermostat or a bad fan relay. If that is not the problem, you will have to get someone with an ammeter to measure the current draw, and start pulling fuses until you find the culprit.

hi its rob sounds like ur battery needs changed when a battery is left to go flat the cells start to buckle each cell is two volts if u loose just one of these the battery will not hold its chardge.sometimes u can get intermited chardge were it will be ok one minute and the i will just dye the next

If the battery is charging and holding a charge all day then you could have a short some where that is draining the battery overnight.
