Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
I did write back on the 18th requesting more info on your question as to what help you required .does fan only run when ac on ?not running without ac on ?
fan should run to cool the warm gas inside condenser .wont come on instantly but after ac has been running for a couple of minutes fan will come on and off as needed .does cooling fan work when engine is left to get warm ?
the fan on the engine runs full time then when engine gets hot one of the electric fans cuts in and out to further regulate engine temperature .the other fan is for ac
its either a wiring issue to and from the fans or a temp /pressure sensor fault on the ac system .have you had ac scanned for fault codes?
it screws into receiver drier behind the drivers headlamp
im goimng to opt out my info on this model is restricted to more detail another tech may have more detailed info
