My 2002 Sedona is having electrical problems; power window, power door locks, power seat, interior lights (ones that turn on when doors are open), the chiming noise that the car makes when you don't have your seatbelt or when you leave the key in the ignition when the car is off= all these don't work. What could it be? All fuses work, and fuse box has power. Also the gauge lights and head lighst only come on when switch is in the automatic position (not when it is on the small lights or regular lights position).

Your best bet , take it to a qualified repair shop .

Door ajar switch problem more then likely or wiring issue . The BCM - body control module won't turn off interior light , let door lock because it think's the door is open . The door ajar switch is a input to the BCM .

The first thing would be to have it checked for DTC'S - diagnostic trouble codes . Also check with an enhanced scan tool to see if the BCM shows ajar switch data (open or closed ? Do you know about body electronics ?

open door find which wire going to powerr lock cut it or take door panel off reach in and unplug plug on power lock motor

had this problem last week ,the switches on the door are faulty try disconneting one at a time to find the faulty one ?

Just to get the interior lights off to save your battery, you could pull the fuse. Refer to the service manual to determine the proper fuse.

To fix the problem, i would suspect one of the door switches is faulty.

It could mean the rod connecting the handle to the latch has broken. You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. and you can access the innards of the door

Sounds like you may have a bad ground clean battery terminals!! get wiring schematic!!!! Good Luck!!!!

Sounds like you have a serious electrical problem that may require a shop (dealer) to repair. Have you tried removing the interior bulb that you replaced to see if the car goes back to the before state? I would recommend that you take it to a professional as electrical problems can be tricky to diagnose especially if you do not have the tools and expertise.

check for an open door ( all doors ) , defective courtesy light door switch, or short in interior light electrical circuitry.
