Windos not working no interior lights at all no centerl locking working, no back spkears working

check the fuel injector at the connector to see if you have both voltage and ground at the injector

-Check the relay. It might stuck on.
-Basic check:
-Leave the hoop open and locate the relay. Then lock the car
and now remove (Unplug) the relay. If the light is gone
then the relay is bad. (It stuck on On Position)

Good luck

Check the fuses sounds like a fuse problem the often dont com alone

i was working on my stuff and then it all when a way and if all my stuff is hucked up all my spkears wires are not working at all but i did fix it my hucking all the wires right in to the back of the head unit help me....

Check the fuses first, you may have shorted a wire.

try to test the battery and put a load on it. with a low battery sometimes the computer acts up.

hi ya it seems one of the door switches is broken or disengaged on each door frame you will find a push in switch witch operates the interior light, door warning light on dash and remote locking if one of them is not working it will show on dash as a door not closed it will prevent the interior light from working and also stop the auto locking system from working properly the locking system is connected to the interior lights
Hope yhis helps

Check your fuses, if ok then put your ear against the door and listen for any clicking or watch your interior light to see if powers being drawn. if you hear clicking or interior light slightly dims for a sec. you probably have bad motors, also check your wires to the motors and door switches..Good Luck..Mike

Check all fuses and clean battery cables
