XJ40 Air Con Question

[groomi]

Hi All,
Have a 1990 4.0L Sovereign (XJ40) and have noticed a gradual trend towards only getting cold air from the air-con when the dials are turned to the coldest setting... even slightly towards the middle it is blowing out hot air.

Does this sound like the gas just needs recharging or am I looking at a far more sinister bill?

Cheers Guys... think I'll get it re-gassed and hope that sorts it.

Next question then...

Can anyone reccommend somewhere in Kent / South-east London to recharge a well cared for Sov?
