    AC repairs: the final frontier

    Last week it was time to fix the AC. It was the remaining completely inoperable system on the car and being a fat guy I am no fan of sweating. John (86VickyLX) was kind enough to donate the AC compressor from his car, so on we go. First up, some pics of why I needed to replace the compressor

    this is the compressor that was on the car when I got it. What you're looking at is the hub on the front of the compressor where the bearing is retained. Normally there is a retaining ring groove here, note the lack of a groove on this compressor.

    Best I can figure is that when the original clutch came apart, the rubber grabbed the retaining ring and spun it until it ground the groove away. When I got it, the clutch was partially engaged because the bearing had nothing to hold it. This is the original clutch plate and hub.

    So out with the old, in with the new. I got no pics of the process because there just isn't a lot of room. The compressor is below the power steering pump. To extract it, the pulley comes off the PS pump, a J-shaped bracket that the front of the compressor bolts to and which mounts under the PS pulley comes out, the lines are undone, the rear bolts are removed, then a Tetris-like puzzle occurs to fish the compressor out between the trans cooler lines, the front sway bar, the radiator, and all of the other crap that is down in that area. I probably should have dropped the sway bar, it would have made it easier. Also, there are some odd tubes attached to the compressor and some rear "feet" that hang up on things. Observe, on the "new" compressor ready for install.

    I also found the wiring harness and connector were completely shot, so that also got fixed. I had another plug with suitable length wires on hand, and a connector from Napa was 7 bucks. Some crimp connectors, heat shrink, and wire loom put it all back to right.

    Initial plan was to simply vacuum it and charge it. I couldn't find a drier so I just pumped it for an hour and gave it a go. This worked for about 10 minutes. At some point while I was messing with the electric fan and not watching the gauges, it must have blown the relief valve because I lost most of the refrigerant. Further investigation showed the orifice tube is plugged solid.

    I also found a source for the drier. Old stock, but I did find one. Motorcraft YF-1192.

    So with a fresh drier, fresh orifice tube, and after a lot of solvent flushing of the condenser, I now get 42 degrees at the vents. I did consider replacing the condenser but its basically specific to the Continental. Fitting one of the commonly available Fox chassis ones would have needed some probably minor fabrication work to adapt the mounts. In the meantime its working, so F it.

      I'm glad to hear you got it working! That compressor treated me well. I replaced my original (bad bearing) with that one. That one was sourced from Project 79 a while back in exchange for some trunk carpeting. Hopefully I can get my a/c back in my vic before it gets real hot. Racecar needs a/c too. And I don't mean R255 either.

        In your case, R455 is more better!

          I find that 4 windows open actually works less well than 2 or 3 in the right spot and amount.

          That compressor is quiet too. I'd forgotten what these are supposed to sound like. The one on the Towncar still sounds like a dying air raid siren.

              My original on the Towncar was rattly, the reman Motorcraft one I installed several years ago seriously sounds like a dying ooga horn. Its horrible. Anyone that has ever ridden in my car has heard it. It works fine, which is the only reason it stays.

                Your exhaust was so loud when I rode in it... I couldn't really hear anything else.

                  yeah the drone is something that I'm really quite tired of. Its really bad at about 50 in OD, which seems to be a speed I spend a lot of time at. I did put a bunch of sound damper in the trunk and that helped but now instead of one really sharp loud peak, its a wider but less loud band. Maybe I need a second layer.

                  Tonight's project was fairly simple but effective. I tripped across some info on another forum that told me that 90s-early 00's Cadillacs had a Homelink compatible garage door opener in their overhead that pops right into the Lincoln overhead. These can be had for about 20 bucks, so I bought one. As advertised, it works fine. Much cleaner than the keychain or visor clip opener method anyway, and it makes use of that slot in the overhead.

                    Oh, neat. Almost looks like it grew there.

                    My Town Car has a similar drone. LoPo so it can't be as bad as your '86.

                      What is the purpose of that slot with the trap door on it? Is that to plug in a garage door opener?

                        Yep, thats the garage door opener slot. THe actual Lincoln pieces are very rare, and completely obsolete now. Its the old style thing with the DIP switches and all that, and it requires the companion receiver to wire into your opener. If you manage to find all the parts, it probably still wouldn't be compatible with most openers made in the last 20 years. Handily Cadillac must have contracted with the same vendor Lincoln did, and they kept the same physical form factor so the late style Homelink openers plug straight into the 1980s Lincoln console and work fine. Visually its not a perfect match, but unless you're looking close its hard to notice. Most importantly to me, it works, it wasn't expensive, and required no effort on my part beyond getting on a ladder to push the button on the opener.

                          It would probably work if you wired it to the main wall button. All it needs to do is short the 2 leads there to trigger it.

                            Possible, but finding those parts is like hens' teeth. There is a receiver on ebay now for $150, I haven't seen a transmitter in a good while. I got this thing for 20 bucks and it works with no nonsense.

                                I got a haul of junkyard parts, so in the coming days and weeks a lot of that will get installed. In the meantime, a super minor parts update. I de-hooptied the replacement rear tail lights. Someone had added plastic "chrome" trim all over the lenses and it looked stupid. Left and right lenses, so you can see what it should look like vs what had been poorly done.

                                The mostly unsorted pile. There is about 1/2 an interior in here. 3 door panels, 4 door seals, sill trim, B pillar trim, the trim above both doors on the inside, window run felts, C pillar panels with the rear map lights, a non-compass overhead console just because, an instrument cluster, and probably other crap I'm forgetting about.
