Question
While running... A/C shutoff, blower went to high and vented through defrost ducts. Fuel and Climate control centers went dark with only a "c" on each. Next start, centers and radio display started flashing along with a few warning lights coming on. Shut down and next start...back to case 1 (just "c"'s) Guess a new BCM is in order???

Answer
EXACTLY RIGHT.

If you replaced the radio, Do NOT install a new BCM until you get back to me.

If you have the correct GM DELCO radio in the car, Replace the BCM and CLEAR (erase) the codes via the climate control panel IF the check engine light remains illuminated after you install the new BCM.
