Hydraulic Fans

[53XUS]

hi, i have a Lexus Ls400 which i got recenty imported for me, the car runs like a dream an everythin works until yesterday when i was cruising around an noticed the temprature way above its normal (just above halfway), so i imeediately pulled ovr n shut down the engine to let it cool a little, i started it a little later after that an noticed that the fan wasn't working

the pump for the fan is a brand spankn new one, an was put on for me just as i got the car, the aircon has also stopped working an refuses to click on when i turn it on, Is there a Fuse / Solanoid that controls these that could have gone?, im just lost as where to start.

any help appreaciated

thanks

If you lose refrigerant from the aircon it won't click on.

The front fan or fans depending on your model rarely run unless the aircon is on

which if you are in AUS is probably often.

The main cooling fan is behind the radiator if thats OK, think aircon problem B)
