Hey 07, did you get your new AC lines from the dealer as a part # of a XK withour rear AC?
My ac stopped working and I found a leak in the line right above the heat shield, above the tail pipe.
What had happened is a bunch of cinders were packed around the line above the heat shield like concrete.
I think it ate right trough it or there was wear between the hose clamp on the heater line and the ac line.
I HATE CINDERS!! our township stopped using them but the neighboring communities still do.
It doesn't look like an easy repair to replace the lines front to back, too many twists and turns.
So I was thinking about just deleting the rear AC.
I was going to stop at the dealer on my way home today and see what they have to say.
