85 XF Ghia 17 Posted October 15, 2018 Hi Guys, ive just recently reinstalled the HVAC on my 85 XF Fairmont Ghia. The vacuum lines on the inside are all accounted for thanks to Searley. I now require 2 diagrams if possible. The hvac vacuum lines set up in the engine bay and the heater core heater hoses configuration. I didnt take a photo of the set before hand. Yes im a Dhead.
