I have a 1997 clk 230 kompressor sport which when you switch the air con on only the right hand fan starts. Ive put a power source to the left hand fan and it runs ok but just not on its own. Sides given are when sat in car any ideas please.

When you stand at the front of the car the two fans that you can see through the grill the left one works when the air con is switched on but the right one does not but it works when power is connected direct hope this helps

If you care to pop up the VIN numbers after 208

The weather being cooler right could be the reason

with the number I will take an exact look for you

Just found this old thread and I had a similar question - as it is obviously colder still at this time of year, is it possible that A/C (in general terms) would operate without either fan having to be on? I ask as I have another vehicl in the family which is doing just this.

Oh yes they are controlled by both temp and pressure, the fan only comes on when needed and does not run all the time
