Thanks, all. The AC is working like a champ after I added another ¾ of a can of 134a. Just in time for the heat here in VA.
Now we'll see if she holds the charge.
Well, looks like I found the source of the AC problem: very bad mechanic.
I have been proceeding from the assumption that the system had enough pressure to kick the compressor on. I was wrong. To make a long story short, based on a friend’s advice to also look at the pressure switches, I...
Thanks for your note, billcu. I will look into this possibilty as soon as I get the AC figured out. BTW, I managaed to completely eliminate the brake pulsations. The rotors appeared to be brand new with no signs of wear or scoring, but were discolored. I took my random orbit rotary sander...
Thank you for your response. I'll look for it there. I had several Merc Grand Marquis with a similar setup for the air compressor. Should have thought to look deeper. But the VLCM is a new one to me and the wiring diagram is misleading or not the right one though everything else on it checks...
OK, so I am not sure I have located the VLCM. The wiring diagram indicates it is in the "lower front center of engine compartment." I cannot find it for the life of me. The thing I found is right of center and about midway down the front grille. The images for this item shows black fins not...
See my intro thread just posted for more info on this car which I just got inspected and registered after 5 years in my FIL's garage.
One remaining project is the AC which does not work. Here is the AC story so far:
A/C is blowing uncooled air. I figured she needed a charge after 5 years...
Wait, how could I forgot about the dreaded bland door actuator. I fixed that as well and now the heat is toasty warm inside. Took me about a day to fix as I go slow and deliberately and still make mistakes. Usually correctable :).
Greetings from Virginia. I just registerd and passed inspection on my FIL's 98 Mark VIII. 168,000 miles. He was a fighter pilot of F-89Cs in the early 1950s patrolling the north pole from Greenland. He is now 92 and not really up to driving, but I've given him some thrills chauffering him...
