2003 jaguar s-type 3.0 my a/c do not work it is blowing hot on cool hot air at the two end vent
if its worked before you might just be out of freon. a dealer can recharge it for you. unless you know where the nipple is on the a/c line. then you can goto your local part store and get the R34 can and refill it yourself
it's either freon or cooling system. my jag did something similiar & it ending up being a leak in the cooling system..I ended up in the end replacing the entire system including the water pump. jags have plastic bits where there should be metal like the water pump. as everyone knows plastic wears out over the yrs so I recommend checking those as well. Hope that helps :)
