Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Additional investigation has led to the conclusion that the sounds I am hearing are coming from one of the fans ( I understand there are two), which maybe will fail "someday".
Therefore the recommendation is to do nothing at this point in time.
Other than this increase on "noise level" the air/heater system is perfect.
I went and got a second opinion, and got the same answer. So I am comfortable.
Thanks for your pointed question.
