had a good look just now, and yes there is a compressor but no condenser!
Is there an evaporator fitted inside the HAVC unit? What about the AC controls in the centre console, hoses, etc?
My 1985 244 (Reddington, previously known as Big Red) has a York compressor fitted to the engine, but has no condenser, evaporator, or any other AC components. Looks like the compressor was installed in the factory, but the first owner didn't opt to have the dealer fit the AC.
If you have the rest of the gear fitted, the condenser may have been removed due to a front ender by a previous owner and never replaced.
Pic below shows the LH side view of an HVAC unit removed from a car and now sitting on a trolley at a 45 deg angle in my mainland shed. Note where the two rubber hoses spring forth from the box - they're the AC hoses; the TXV can be seen connected to one of them. The black butyl-covered rectangle to which they're connected is the evaporator.
(hmmm, just realised that one's a 73 model HVAC, but they're very similar)
Chances are that if you can't see the TXV on the LH side of the HVAC, you don't have an evaporator in there.
If you're adding an evaporator to the car, there's a rectangular blanking plate on the LH side of the HVAC box which needs to be removed. Then for RHD vehicles, the evaporator slides into the cavity just underneath and below the air intake, from the left hand side of the HVAC. You don't need to pull the whole heater box out to fit an evaporator (dealers didn't) but there's 30+ years of dirt in there now, so I would these days, just to clean all the leaves and dust out of there.
