Hi,

I'm getting power on the lt blue wire to the door lock solenoid all the time. I'm suspecting a bad control module because I disconnected all the lock switches and I'm still getting power. I guess it could also be the aftermarket remote starter which has door lock control too but want to rule out the control module first. I read a previous post which says the Door lock control module is part of the BCM but the diagram i have doesn't indicate that so my question at this point is where is the door lock control module located on a 2002 chevy express 1500 and does anyone know where the junction terminal is where all the door lock wires meet (lt blue lock signal)?

Thanks

 

I am not familiar with this vehicle but I suspect it is BCM controlled, other then the the receiver for the keyless entry which is a separate module...

 

is the BCM the module under the driver's seat in my model van ?
