If your aircon blower does not work, strip it down to the printed circuit board. There is a Tyco 40 amp relay with a single soldered pin 5 on the 12v blower supply. The output of this relay goes to the rotary blower speed control switch. Mine had a dry joint from over heating due to a too small solder pad. The job took half a day, but saved a heap of money on a new aircon control unit.

On the same subject if your Vito AC won't refill check for holes in the condenser.
Mounted low down behind the front bumper it's an invitation for stones.
When I replace mine I intend to protect it with a fine mesh grill in front, tough plastic preferably.

Heater blowers can pull 15 amps, many components are hardly up to this high current, and many mods over the years. Pleased you have managed a good fix.:D:D
