SOURCE: heater core replacement
OK, Ifound the problem with mine. Dont unplug your air dryer. I checked the 2 hoses coming out from the heater core and still one was hot and the other not hot. The top one comes from the radiator fill tank and the bottom one comes out of the core and goes around to the front and into the water pump. I disconnected both close to the core and could runwater through both directions so upon further examination, I disconnected the hose at the water pump and no water flow. The hose was plugged up with something. Once I cleared it with a hanger and reconnected it I had water flowing through the core and great heat. Hope this is your problem too as it is aneasy fix

SOURCE: replace heater core on 1992
It appears I was incorrect about removing the dash assembly, here are the instructions from a Buick owners club.
Under the passenger dash is an access panel that will allow you to remove the heater core, it really isn't that hard, there are lots of little dash screws and panel screws to remove before you get where you need to be but at least it is roomy. The AC evaporator is located by the heater core. I will give you a tip. I changed mine last year and the heater core that I ordered for my 92 Roadmaster was not correct, when I took my old one out and matched it in a book at the local part store, the heater core for my vehicle was listed as a 96 Caprice???? The car has been in my family since it was purchased new and the heater core had never been changed!!!! Explain that one!Oh yeah, one more tip, if your heater core is leaking, this access panel lowers towards you, if there is nasty sweet smelling water in there it will pour all over you, be careful! Caprice parts are the same as a Roadmaster,so if you ever need anything just look up caprices

On the inside trim, you can remove screws (these screws may be covered by filler pieces or may be visible, or they may require you pry a plastic piece off that covers the screws) that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect any other wiring that may be attached to the door.
