I just had this problem. It's the relay switch under the dash on the passangers side. It cost about 75 bucks for the part and anyone can do it. It's just 2 screws.
Have you had the alternator tested? It may not be regulating the energy to the battery, causing it to drain
On my espace a wiring fault turns on the ignition circuit at random draining the battery if not spotted. This is without the keys in the ignition. I fitted a battery isolater switch and use this to make sure it dont drain while parked up. seems to happen mostly when frosty etc.
most of the time the diode circuit will burn out trying to keep a defective battery charged, which results in overheating or increased amperage for the charging circuit which includes the diodes.
On my 2002 the ignition switch was hanging up causing a similar situation. A shot of WD40 into the key hole cleared it up, over a year ago.
Something must be draining the battery while it is not running. Usually it is caused by an interior light being left on either inside or perhaps the trunk or one of the doors were not closed completely and thus causing the interior lights to stay on and drain the battery. Otherwise, this will continue and you should plan on replacing the alternater and/or battery
Check your alternater. Sounds like it is bad in which case you are running just on the power from your battery which won't last long.
Something is causing a drain on the battery even with the vehicle off and nothing turned on. A good mechanic can do a drain test on the battery to see what may be draining the charge. A dead cell in the battery itself will also cause the battery to go dead. Disconnect the negative battery cable overnight and if the battery is dead the next morning it has a dead cell and must be replaced. If not look for a light that is on or a relay that is stuck.
It is the relay that energizes the clutch on the air conditioning compressor. Yes it does fail and remain closed after ignition is turned off, causing the battery to drain.
Does you car starts??? if no that means your battery doesnt have enough adequate power...there are 2 things... your battery maybe damaged or your alternator is damaged causing not charging up the battery..but if your car starts..try to reset your computer by unplugging the negative battery then turn the ignition on for 20 seconds then plug the negative battery back..now check if you still have the battery lights on..cheers..
check ignition switch and efi relay
If you don't keep an otherwise good battery charged in freezing weather it can freeze and break the case. If your battery won't hold a charge because something is draining it, you should disconnect a cable and charge it then reconnect it before you try to start the car...or fix whatever it is that is causing the draw. It is better to keep the battery charged so you can start the car when needed. Consider hooking a battery tender to the battery if it discharges because of long-term disuse.
