Question Hello, ok i have no dash light brake or dim lights, the only way i have ANY lights is we hold the brights on, we believe it's the BCM, but cannot find it, what do you think?
Answer Hi Amanda,
The bcm is located on the back side of the fuse box, under the dash. The two are electrically linked to one another, and are separated by sliding them apart. But I would question whether the issue is with the bcm. Are you saying that you only have high beam headlamps, and that you have no low beam headlamps and no brake lamps, and no illumination lamps for the instrument cluster (or do you mean no warning lamps on the cluster?)?
The brake lights are not controlled by the BCM. Instead check fuse 13 in the box under the hood near the battery. If that is OK then check the brake switch operated by the lever of the brake pedal.
The low beam issue could either be the dimmer switch itself being faulty, or the low beam relay which is the 5th one (last one) in the in-board row of 5 relays in the underhood fuse/relay box. Try substituting another relay in the box with the same part number for the low beam relay to see if that corrects the low beam problem. The BCM does play a role in the low beam light circuits but I would first verify the relay and including fuses #6 and 7 in that underhood box and the fuses that power the bcm (see below).
On the dash lights, are the lights for the A/C heater control also not working, or are they OK? I would check fuses #2 and 6 in the fuse box underdash as those power some of the circuits in the BCM that may power the dash lights.
Only after you do that would I look at replacing the BCM.
Roland
