Bcm location I need to know the location of the bcm for replacement because my interior lights are out and all leads to bcm is bad

CIG LTR 1 fuse 20 amp - location ,under hood fuse box . Which interior light's ? One's that can be dimmed or one's that can't ? Light's are controlled by the BCM - body control module , do you know what that is ?

Your vehicle has no BCM ! Which interior lights ? dome , courtesy , insturment panel ? Dimable light's ? Stuck door switch ! Find a wiring diagram at http://bbbind.com/free_tsb.html ! Do you know how to do basic automotive electrical testing ? Videos on youtube . The wiring diagram is showing a dome courtesy lamp relay , if the contact's were stuck closed the light's would stay on . But there is no BCM .

Most times it is the light switch when none of the lights work. Can you manually turn them on? This over rides the BCM. Interior lights are controlled by the BCM. Try opening the passenger side door, see if they come on. If so, replace the drivers door latch, inside the door. If still no lights. The BCM needs scanned for codes.

there must be a switch on the actual light fitting to set it to 1 always on , 2 always off , 3 on when door opens , check the switch position

What all did you disconnect ? Did you disconnect any connectors to the BCM - body control module ? All the thing's your having troubles with are controlled by the BCM . The wiper switch is an input to the BCM , the BCM controls the wipers by energizing two different relays . wiper on relay & wiper high low relay .

Since horn didn't work, tried to take off dash ???? Why ? didn't need to do that . Do you know what a relay is ? Horn relay is located in the under hood fuse / relay box . You could have tested right at the relay base - where it plugs in .
VEHICLE RELAYS Operation Diagnosis

Diagnosis by parts replacement is getting a little frustrating and expensive is it? Did you bother to scan the BCM for fault codes before replacing it? Have you scanned your new BCM for fault codes?
Have you verified proper operation of the Inadvertent Power Relay? Have you verified proper operation of the courtessy lamp relay? Have you checked to see if the BCM can command the courtessy lamp relay on? Is the BCM recieving power from the Inadvertent Power relay? Are your courtessy lamps recieving power from the Inadvertent Power relay? Is the courtessy lamp relay providing a good ground for your interior lights?...These are just SOME of the possibilities - that is what DIAGNOSIS is for...

What Else Could Be Wrong?

the BCM that cotrols the interior lights most likely is bad. the central timer module in the bcm is not turn the lights off.

you bcm (body control module is bad) to have the dealer replace it will run you about $400. a quick fix for the reverse light is to splice 2 wires into the wire for the center plug in your trailer wiring. now run a wire up to each reverse light, cut the green wire to each reverse light and **** conect them up. this is a seperate revers feed than the one from the bcm. the dome lights remove the light cover on the second set of interior lights (the one between the drivers seats). the two side bulbs are map lights the center bulb is for the dome lights. run a jumper wire from the right or leftside socket to the center socket. you dome lights will now turn on with just the use of that switch i replaced the back bulbs with led's soo there is no extra amp's being drawn. you could bypass the bcm but i could not find any wiring diagrams for it and i dont know if it can take the added amp's

this is the bcm. replace the fuse block/bcm with the same exact numbers. youll need to pull it out first and alot of salvage yards will have these.

some chatrooms say its in the right side kick panel under the fuse box, I never looked for it myself, hope you find it
