I've noticed that when the air con is on the radiator fan runs almost all the time, even when the engine is cold. By almost I mean it runs for 10 seconds or so, then stops for a few seconds then starts again. Over and over. Turn the air con off and the fan stops immediately.
Air con seems cold, and was re gassed not long ago. Dealer seems to think this is normal, but it never used to do it.
Anyone seen anything similar?

This is absolutely normal. It will run for more than 10 seconds when the weather heats up or when you demand the lowest cabin temperature possible (if you have the digital A/C controls).

:yeahthat:

Completely normal and would be an issue if it wasn't doing this as the condenser by the radiator wouldn't be getting the correct airflow for the AC to work correctly.

Probably find the system wasn't working correctly before the AC was degassed.

Thanks for the replies, thought it was a bit weird it coming on and off rather than just running but I'll try to stop worrying about it!
