Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to help with this today.I apologize for the delay.
If only part of the fuse panels are receiving power this can be a number of different reasons from a faulty electronic ignition switch to poor power connections leading from the battery to the fuse panels or even damaged wiring.If you can tell me which fuses do not have power or at least some of them this will help as I can look at some diagram info to see what I can locate on these.I don't see this as the ECM or anti theft at fault as this won't cause a power loss like this here.

In the same fuse box as this IGN 1 fuse there should be an IGN 1 relay.Does this relay click at all when turning on the key or if you tap on this relay does the power come back then?
Is there any way you can check for any broken wiring at this fuse panel?
I apologize for the delay.
The wiring or electronics in or leading to the door usually wont cause this fault here.This sounds like a possible wiring fault at the fuse panel.If you can I would check the wiring at the fuse panel to see if any issues are found needing repaired.
