Something strange is happening. I parked my 2008 Suburban int the garage for 3 nights and now it will not crank over. There is no dome light, the brake lights don't light when you put your foot on the brake... very strange.

Also the key fobs do not work.

Anyone have any ideas

 

I think its the BCM after doing hundreds of google searches. Any had experience in swapping these out?

 

does anything work? dash lights? radio? is the battery good?

 

There a warning lights on the dash, gives a warning about stabilitrak and service 4 wheel drive system, other wise nothing else works, no rear door, no dome lights, no brake lights... etc.

 

Basics basics, start testing from power source forward.

 

I have power where it needs to be. I can jump the starter relay and it cranks. I don't have key fob's, dome lights, backup, turn or parking lamps. I cant access the rear hatch, the rear windows will not roll down etc.

 

I just noticed that the radio says theftlocked. But I get no security light on the dash...

 

sounds like antitheft issue

 

Yes, it does, but there is no security light on the dash...

 

key in run position and run all fuses?
