Check that your doors close completely (windows do not hang up on the convertible top). Also after your battery has drained or cables removed (to charge or replace battery) the power windows on the convertible model must be "retrained" to close correctly. The procedure is in your owner's manual but basically it is to sit inside the vehicle with door closed and lower the window then raise. When the window is fully closed do not remove your finger from the "up" button but keep depressed for approx 25 seconds. If properly done and assuming the battery has enough charge, when you open door the window should lower automatically a fraction to clear the convertible top then automatically raise when the door is shut. Do the same for the passenger door.
Yes, IF the ignition SWITCH was left ON. I suggest charging the battery, and then have it tested at Autozone both of which are free.
Either the switch was left in the wrong position, or the thing is defective. The dome lights draw enough current to drain the battery overnight.
bad ignition switch, bad battery, bad alternator/regulator,
There's something left in the car that use power even when the engine is off. Can be a dashboard clock, can be the vehicle alarm system, can be the stereo. The battery can also have a dead cell which will drain it overnight.
Almost anything. On newer model vehicles, the engine's computer drains the battery constantly, as does the stereo. Short circuits can cause a drain. Any electrical system that is left on will drain the battery. Even a disconnected battery will lose charge over time and the older the battery, the faster it drains. Also a battery with a dead cell will discharge itself, usually overnight.
Check for proper operation of alternator and battery, if thay are proper; check for parasitic drain.
Dead cell in the battery or the ignition or lights were left on.
Have you had the alternator tested? Often a bad internal diode can drain the alternator overnight.
There is a good chance that your battery has a dead cell. It will act like a good battery of you start it every so often, but if left overnight, it dies.
YES
that happen to me. everyday in the morning the battery was dead until i found out it was the relay for the fuel pump, it was bad and it causes to leave the fuel pump on all night. maybe your is doing the same thing.
Anything left plugged in and powered up can drain the battery.
