How to Replace a Body Control Module

by Shayrgo Barazi

You have gone through all the diagnostic flow charts available to you and finally come to the conclusion that the body control module is at fault. Replacing it is generally straightforward, but if you don't follow the proper procedures, you can do more harm than good.

Step 1

Disconnect the negative terminal on the battery with a wrench or ratchet.

Step 2

Locate the body control module. Your factory service manual can tell you where to find it, but the module is typically behind the glove box or underneath the center console.

Step 3

Remove the glove box or center console by removing the Phillips-head screws and bolts holding it in place.

Step 4

Use a ratchet to pull out the bolts holding the body control module in place.

Step 5

Push the connector clip in with your fingers, and pull the connector firmly. You will have to use quite a bit of force.

Step 6

Install the new body control module, and insert the connector.

Step 7

Reinstall the glove box or center console in reverse order of disassembly.

Reconnect the negative terminal of the battery.
