I'll be checking for loose connections in the morning and I'll check to see if there's power at the blower motor....I'm thinking it's the switch assembly because the heater doors are not working but the A/C selector does make the clutch engage.

What type of motor?

Engine cranks or starter won't engage?
Is it a Mercedes?

If you turn the key but nothing happens , like the starter won't engage, it is very likely the Mag Switch. These are cheap to replace but if you ignore them too long they will destroy your starter which is not cheap.
