The auxillary fan ahead of the radiator comes on only after the A/C develops a little pressure (4 bar IIRC), i.e. it is doing some cooling. It does not start simply because the A/C has been turned on.hi
no it blows fine(the motors blow good) the problem is that the aircon takes ages to come through cold and even then its not that cold. When i turn off the aircon and the temp gauge shows the lowest on the lcd as 16c it still comes through as warm air.the aux fan for the aircon is not coming on at all (the one in the front grille).it was working fine until i changed the compressor though
If you have the new PWM controlled fan, simply applying 12V will do nothing. In fact, that fan should have 12V at all times already. A good fan runs only when it is receiving the PWM signal from the engine controller.hi rdl, thanks again for that. I think the best thing is is for me to put a live to the fan to see if it works first then if no then a new fan probably,or to change the pump again to the original one and to fully charge it to see if the fan works then if not change pump again for another.
