Default Battery/Headlight switch?

Ever had this issue w your Volvo

HELP! 2006 C70 T5, battery/ignition/headlight switch? Car runs fine, come out next morning, car won’t start. As soon as I turn key driver window goes halfway way down. Car is dead, won’t even take a jump start. Also even with headlight switch off and the keys NOT in ignition the headlights are on. Remove battery, charge. Reinstall charged battery, car runs fine for one week then, EXACT same thing again?! Any clues? It’s almost as if the lights were left on overnight but weren’t

A good first step would be to scan all the control units with a compatible scan tool.

You might have a problem with your CEM - but the first step would be searching for error codes that might guide you in the right direction
