Have a 2003 CLK500, when I push the A/C off button cold air continues to
come out the vents, seems as if it is not shutting off the compressor. To
shut the compressor I must shut the fan then when I turn on the fan the air
gets warmer as the compressor shuts off. Seems like the microprossor is
confused. Any tricks to get it right or am I off to a trip to the dealer.
