Hi there anyone help me the heater blows cold more than it does hot Evan when the heat comes back it's not hot evan  on high just seems to be on the drivers side 

Google the following.......

"jaguar dccv fault"

its the valve that splits the heat/cold settings in the dual zone climate system, prone to seizing and if left they can burn out dccv circuit board leading to much expensiveness!! 

not a hard job if your good on the spanners, just fiddly and expensive, about £90 for a good used one and considerably more from jaguar!! 

There used to be a jag breaker near Johnstown but I can't remember his name, he closed his yard but still had a load of spares when I phoned him up about a year ago.

Thanks Andy will check it out the guy you mean is in legacy Kelly's if it's the same one

Yes, that's the one.
