Check your fuses, try replacing them all with quality copper fuses. If that doesn't help, and no other electrical issues (i.e. is the PBU getting any power, and is it properly grounded?), then I think it would be safe to say your PBU needs to be either repaired or replaced. Note that you may also have other problems that you cannot detect now due to non-functioning PBU.
