.......real bad behind the dash but only when the interior heater/air conn switch is moved to the on position. The air coming out of the vents had always changed to the defroster when climing long hills especially after I changed to 30" tires but now the Xj only has to see a slight upward grade and all the air blows from the defroster vents.
One test I did that confirms the locality of the leak was to park the XJ over night with the heater switch off then check for vacumn in the morning. There seem to be no loss of vacumn next morning. However if the switch is turned on with the engine off, the vacumn leak out in less than (well close to) a minute. I took the dash apart to look at things behind there but all I see is a bunch of spaghetti hoses dissapearing in a harness wrap.
What is the easiest way to locate the culprit end convinse him to act the way he is supposed to?
