Re: Evaporator Core Access? (2006 Grand Marquis)

Its a pain to get to. I just replaced mine in my 87 grand marquis and literally had to pry it out. There are screws that hold the two halves of the enclosure its in but mine still didnt seperate so I had to use a breaker bar.

The far easier way to find out is to run uv dye in the system and watch the drain line. The evaporator will leak into the enclosure and out the drain line along with the dye.
