    I was going over some of the features that came stock in my '88 lx and it seems that the previous owner has undone a lot of stuff.

    To start, they bypassed the A/C by just running the belt on the alternator. I can't tell if it's factory or dealer, but I believe it's factory since the inside has a button for it that looks flush with the other climate controls. I was going to route the belt back on the AC, but it looks like there's not a connector. I looked on Rock Auto for a reference image and still couldn't find that in the engine bay. What other connectors would it be grouped with?

    Second, the turn signal stalk had cruise control buttons. I traced them into the engine bay but I couldn't find where they connected to the servo on the inside. I found a connector that was plugged with screws.

    I'll take some photos in the morning, please let me know what I should be looking at and taking photos of :D

    Thank you!

    I cant help much, each of my current crop of Escorts are 2nd gen; but as part of re-routing the belt so it spins the a.c. compressor again, make sure the pulley on the a.c. compressor is free to turn. If it is like the 2nd gen compressors, it has a bearing inside, part of the pulley, which has no way to be lubed, and is probably as old as the car. The bearing has to be pressed out and a new one pressed in, being careful not to distort the clutch assembly. And that cant be done with the pulley on the car. To eliminate the possibility of that bearing failing on the interstate - I removed the compressor and installed the 'compressor bypass' item rockauto sells.
    On my nephew's S10, the a.c. compressor pulley was very hard to turn (would skid the belt) until things got hot under the hood. Since no one made a bypass pulley that we could find, we put on a rebuilt compressor, even though the a.c. system no longer worked or held a charge of freon.

    @denisond3 the pulley spins freely, but I'm assuming if they took it off it wasn't for the added power and it just didn't work. I'm going to hunt for the right replacement compressor, but I'd like to test this one just in case I can save $200

    I'd be concerned that someone put the A/C equipment into the car thinking it would have A/C before they realized that you need the proper wiring to do so - this is something EVERYONE overlooks when they consider putting A/C into an 80s Escort/EXP that didn't originally have it. They also never realize that the plastic duct work behind the dash is special for A/C cars and without the proper duct system you can't have A/C. This is a neat way to see if you have A/C or not, behind the radio will be a big plastic box for the heater core that is relocated when the A/C's evaporator core is equipped. If you don't have that big plastic box behind the radio 1" off the ground you probably don't have A/C, if you don't see the A/C lines going into the firewall stop now before you spend money and time on something you'll never be able to have.

    Share a photo of the compressor's connector, the early factory compressors had just a 2-pin connector that's easily broken but easy to MacGyver a permanent solution.

    The cruise control has me baffled as well, it's the same system they used from the 70s all the way to the early 90s. It's a vacuum-actuated system but the steering wheel or stalk control wiring doesn't seem to have anywhere to go. There has to be a vacuum valve controlled by an electrical solenoid or something but I haven't been able to dig into my few cruise-control cars to find out.....

    It's got the lines and everything, I took a photo of the VIN just in case that could tell you if it has factory ac.

    If the compressor is for good, I'd like to just run that instead of a new one. I'm not for sure but I think there's R12 still in the system. That or there's a vacuum, I didn't hook my gauges up to it.

    Looks like a factory A/C system, that burnt plug is near the compressor but I don't think it's for it, all the compressors I've seen use a different looking 2-pin plug but I haven't seen enough 88 A/C models to declare that as fact.....

    Sadly the VIN only tells you the
    Model year
    Safety restraints options
    Assembly plant
    Engine option

    I'll look in the wiring diagram in the Haynes to see if I can determine where to find the cable, or add one if it was cut off.

    At first I thought maybe it would run through the center of the belts where nothing hits, but I doubt that would be safe. I could just be missing the cruise control servo completely, my friend has an '84 GLX with cruise and it has a large round object that isn't anywhere on my car.
