No, the BCM it says it is plug and play, you can get a rebuilt unit by searching google or ebay. Here is how the job is done and the location of the BCM so you can do the repair yourself.

REMOVAL
1. Disconnect and isolate the battery negative cable.
2. Remove the lower instrument panel silencer.
3. Remove the knee blocker and reinforcement.
4. Disconnect the five wire connectors from the bottom of the Body Control Module (BCM).
5. Move bulkhead wiring aside.
6. Remove the screws holding the BCM to the bulkhead.
7. Remove the BCM from the mounting bracket.

INSTALLATION
1. Install the BCM to the mounting bracket.
2. Install the screws holding the BCM to the bulkhead.
3. Connect the five wire connectors to the bottom of the Body Control Module (BCM).
4. Install the knee blocker and reinforcement.
5. Install the lower instrument panel silencer.
6. Connect the battery negative cable.
7. Verify proper operation of BCM and its functions.
