Body Control Module (BCM)
Under the I/P below the radio on the right side of the center console.
Do you know what the purpose of the BCM is ?
The body control module (BCM) has a bussed electrical center integrated into the housing. Body control relays and fuses are installed directly on the BCM, which simplifies wiring and junction blocks on the vehicle. The body control system consists of the BCM and its associated controls. Battery positive voltage is provided to the BCM from IBCM BATT 1 fuse and the IBCM BATT 2 fuse in the underhood fuse block. The module grounds are wired to ground G201, G203 and G305. The BCM is wired to the GMLAN High speed serial data buss, and the GMLAN Low speed serial data buss, as well as discrete input and output terminals to control the functions of the vehicle's body.
Serial Data Gateway
The body control module (BCM) in this vehicle functions as a translator between the High and Low speed GMLAN busses. The 2 communication protocols use the BCM to translate communicated serial data messages between the control modules over the 2 serial data busses.
Power Mode Master
This vehicles body control module (BCM) functions as the power mode master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
Serial Data Power Mode Master
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:
Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs Off/Run/Crank, Accessory, and ignition 1, to distinguish the correct power mode. The ignition 1 circuit is also routed to the Run/Crank relay for relay controlled power feeds during the appropriate power mode. The BCM, after determining the desired power mode, will activate the appropriate relays for that power mode.
Reprogram the body control module (BCM) after replacement. Refer to Control Module References .

Yes -to get to it, there is a hidden screw in the middle of the carpet there on the right side. You may need to remove the door sill as well by prying up the black plastic strip and removing the three screws.

I have a 2006 HHR with no reverse lock out. I have read replacing the shifter assembly with a 2009 will cure the problem. Will this later shifter work with the cables without problems.

Yes 2006-2010 shifters and hardware are 0interchangable., check brake pedal to switch adjustment for solenoid interlock release arm, interlock solenoid may be damaged or misaligned. when you depress brake pedal the brake switch sends signal to the BCM (Body Control Module) in turn sends current to interlock solenoid causing arm to retract releasing shift lever. Please note that interlock solenoid is mechanically actuated to the extended lock position when interlock solenoid is not electrically energized.

Speedometer,milage counter not working

Because nearly everything on the HHR runs through a control module, I believe that you will find that the Body Control Module has gone bad and will need to be replaced. They run a little over $300 and need to be programmed by the dealer, so this is not a casual garage replacement. Sorry.
