The heater core on a 1984 Cutlass Supreme is located under the blower motor on the passenger side of the car, under the hood. First you need to remove the blower, and the hoses connecting the heater core. Replace the core, re-attach the hoses, and put the blower motor back on.
To do it correctly, get a manual ftom a parts store or AUTOBOOKSONLINE.COM. They have pictures and everything
On a 1982 there are two doors, one in the heater outlet and another behind the glove box. May be the same for 1988.
take the 2 hoses off to the heater core and get a hose and flush out the core through both hose fittings on the firewall.
Could be, low on coolant, stuck open thermostat, plugged heater core, temp blend door malfunction,
Either one of the heater hoses are leaking or you have a freeze plug on the side of the engine leaking.
Get it warm and feel both heater hose's at the firewall and see if both are warm. If not, the heater core is probably plugged.
