I've got an intermittent problem that seems to only happen if it's cold out (mid-40s or lower). When I get to the car (before even opening the door) I can here a clicking and see the Security light flashing as it clicks.
I've located the clicking noise to the BCM under the passenger-side dash. It keeps clicking maniacally (like 4 or 5 times per second, but not at a regular pace), and the Security light flashes with it. If the door is open (or the door closed and interior lights on), the interior lights flash with the clicks as well.
When this happens, the car won't start if the Security light has flashed up (as though the VATS system is preventing action), but if I can get the key turned between clicks it works. After starting the engine, it sometimes stops and sometimes keeps going until the car is warmed up a little.
I know it's the BCM that's making the clicking noise, but I wanted another opinion before buying a new BCM. Is there anything else in that electrical system that could be causing this issue? Could it be low cold-voltage in the battery? Could it be a bad ground wire? Could it be some other component?
I've checked the connectors, and they all seem fine. I wouldn't think the cylinder lock would cause this, since it happens whether the key is in the ignition or not. Any advice before I spend the money on a new BCM?
This problem lasted all last winter, then stopped as the temp warmed up, and now it's starting again (but only on cold mornings).
