Question about 2003 Mercury Grand Marquis
Pull the AC control head out and check for vacuum at the back of the control, if there is no vacuum or very little then the plastic line is pinched where it comes through the firewall on the passenger side behind the kick panel, that is most often the spot it gets squashed. am sure it is allot less than $800 to fix, maybe $200.00
