i have a 2001 tacoma and the dome light will not come on when the doors open. it was working but the other night it died. i know it not the door switches, bulb, fuses or power going to the bulb. the bulb lights up when in the on position. the door ground wire is no longer grounding to complete the circuit. tested it with a multi meter. was wondering if anyone knew were i could get the wiring diagram for this circuit. any help would be great.. thanks
