Q: How to fix Air conditioning stopped cooling / no response to AC button in Ford F-150?

Replacement of the BCMC module and the complete AC compressor clutch (according to TSB 23-2130). If an F-150 of this year has a problem with a discharged battery, always listen around the AC compressor with the engine off (or check the current draw). Replacing just the BCMC module without replacing the clutch will burn the module again!
