Silly question but does the freelander 1td4 have to be at a certain temperature before the air conditioning kicks in , over the winter mine didn't engage on the clutch so I presumed it was low on gas, or the pump was kaput, the other week it started working when the weather was pretty warm, last week loads of rain it didn't work (clutch not engaged, today just started the car to keep battery topped up the air con is now working, so is it a temperature thing or intermittent fault when the weather is crap
