heater not getting as hot as normal

Its at normal Temp. About halfway on the guage

Sounds like you'll need to have the climate control system looked at. The system controls the amount of heat delivered to the passenger compartment with an electronically controlled motor that is controlled by the climate control module (computer). You could also have a cooling system that is not functioning properly. It's best to find a shop that can properly diagnose the problem, so find a shop that specializes in Jaguar for the best results. If the engine is ever running hot, then stop driving it and get it towed to a shop. Good Luck
