At the same time the "Service Engine Light" came on the "Air bag" light also came on, the overhead lamps don't work, the trunk button quit working. We checked all fuses in three different locations and none were burned out (under hood, back seat and front passenger seat). Can you tell me where I can find on the Internet a Wiring Diagram of the electrical circuits? I live outside the country in Guatemala.

Since engine light is on I would suggest retrieving the trouble codes if at all possible. This will normally pinpoint the culprit. In this case, I would not be surprised if the PCM is at fault causing these electrical issues. I do have wiring diagrams but will need to know which system in specific you want it for (i.E. Exterior lights, power windows etc.)

We were able to get the "service engine" light off but the airbag light is still on. We can't get the codes to show any abnormality. The wiring diagram we need is the one that shows the interior ceiling light and the trunk release button. Thank you for such a prompt reply.
