Why doesn't the air conditioning work on the Smart 451 anymore?
Years 2007-2015

Answer

If you have problems with the air conditioning on your Smart 451 there will almost certainly be some problems with the dedicated control unit. Unfortunately, this is a known problem among owners of this car. It is unlikely that the car will still be under warranty, but you can try to ask Mercedes for a little discount for the replacement as it is a known problem.
