[W126 Coupe] Re: AIRCON is "Kaput"

[Dan Gardner]

My SEC continues to give me grief,1 year after a r134a conversion its a warm 
as toast.
    The system is not the climate control 5 button unit fitted to most 560 
SEC's but the twin wheel manual model.With ignition on blower fan on II but 
engine not running I cannot hear the compressor clutch cut in when  select 
A/C.Fuses are ok.
    I am aware there is supposed to be a speed sensor,but the CD rom refers 
to the climate control 5 button unit .If anyone can point me in the right 
direction to faultfinding this unit I would be gratefull.

                                                    Kind Regards  Dan
