Answer

hi these are well known for a windshield leak which runs straight into the fuse box , this ruins the fuse box and causes your trouble

Customer Concern:

No start, no crank condition. When the key is placed in the Run position a buzzing noise is heard from the Central Junction Box (CJB). When a connector of the CJB is disconnected, the buzzing noise will stop, the engine will crank but will not start. The THEFT light on the auto lamp sensor will flash on and off in rhythm with the buzz noise from the CJB. None of the relays in the CJB appear to be making the vibrating buzz when a finger is held on it. A couple times it was though that the buzzing relay was identified but when the relay was removed, the buzzing was still present. There is no communication to the Powertrain Control Module (PCM) through the scan tool but some of the other vehicle modules will communicate.

Tests/Procedures:

1. Disconnect all fuses one at a time and check for the fuse removal to effect the buzz. 2. If an associate fuse can be removed which affects the buzz noise, observe the wiring diagram of that fuse to identify how the circuit is affected. In other words, if there is any external wiring circuit that is back feeding into the CJB causing the condition, or, if the is isolated to a short interior of the CJB.
