Power under the hood, power at the headlight switch, the ground I had before wasn't working

Power at the glove box int. Light fuse, and the rap fuse. No power at mall fuse.. What now?

Mall is suppost to have something to do with the BCM.. Witch has to do with security. I looked and looked but cant find anything out of place. Pulled up half the carpet and theres notthing left in the dash but wiring and i just dont see anything.

So i guess i need to figure out what i should be testing on the BCM.. I dont have any wiring in my manual for it though.

put the dimmer switch to dome and check cavity "B" a white wire on the headlamp switch. Its important that the dimmer is set to dome.

CAvity b white wire, with the dimmer on dome, no power. With the dimmer set before dome it's got just under 12v

Is it .01V or 0v?

jay7199

iTrader: (9)

It's .00v

Got the lights on by jumping a 12v power to one of the lights wires.

Do a continuity test on that white wire from the headlamp switch and BCM

The test shows with the switch set to dome the circuit is closed or shorted. With the switch set before dome, the circuit is open.

Let me dig up the BCM schematics. BRB

Here, use these.

According to what I have, get the BCM out, and check pins F and K. If you get nothing out of there, the relay in the BCM is no good.

Check on C3.

And if the relay is no good, I know on the f body cars, you can usually take it apart and it will have a bad solder joint. Heat it up with a fresh dab of solder, and you're back in business

F and K are not orange how ever, K has power, F does not.

What color are F and K?

jay7199

iTrader: (9)

K is orange i think, F is blue.. Looks to be the same blue wire that goes into all of the lights

Apply 12v to that blue wire and see what happens

Sounds like you've got a BCM issue. Check all the voltages going to the BCM from those schematics I posted and see if they are all there.

K has 12v

whitehooptie

iTrader: (2)

What I mean is on C3, check pin B F J K for 12v

jay7199

iTrader: (9)

K and j both orange have 12v but b is a tan color with no power
