faulty diodes or door switches are one of the few things related to doors/locks that can drain your battery. You need to ask the repair guys who changed the Window if any door lock parts were changed and the need to use a multimeter to check the battery for power loss once they fix their error.
That test light method is not a true indication of what the issue is. You need to use an amp meter in the same manner but it has to be able to read at least 10 amps. Keep in mind that if you have the door open on the car that it draws a lot of current.
WHEN TURN OFF CAR CHECK TO SEE IF RADIO TURN OFF.CHECK TO SEE IF INTERIOR LIGHTS OFF.MAKE SURE HEADLIGHTS TURN OFF.IF ALL LOOK GOOD.YOUR POWER DOOR LOCK FAULTY DRAIN POWER.FAULTY BLOWER MOTOR RELAY DRAIN BATTERY.FAULTY STARTER RELAY OR SOLENOID DRAIN BATTERY.FAULT IN THE PCM WILL DRAIN BATTERY.MANY MANY THINGS WILL DRAIN BATTERY.
If you disconnect the negative battery cable and connect a 12V test light between the battery negative post and the negative battery cable terminal the light will burn if there's a draw. Make sure all electrical consumers are off and all doors closed when doing this draw test. If the light is on start pulling 1 fuse at a time until the light goes out, when it goes out that's the circuit that has the draw. Trace it from there.
That is easy to track down, ok full charged battery, then connect an inductive
pickup ammeter that can read milliamps around the positive battery cable make
sure all lights and doors are closed and read the drain on the system anything
more that .003 amperes is excessive remember that the PCM has a KEEP ALIVE MEMORY and that cannot be shut off so
don't worry about that it's so slight that you won't see it. if you see a
drain start unplugging fuses one at a time and lay them out so you know where
they came from, keep goin until you get a drop on the reading and that is the
circuit that is draining current. How long does it take do drain a full
charged battery?Check glove box lights trunk lights underhood
