The blower relay only operates the high speed function. The blower speed resistor operates all the lower speeds. I would suspect the blower speed switch is At Fault. Examine the blower speed switch and the plastic electrical plug that plugs into the switch, you may see the plug has melted.

Like most internal combustion engines with liquid cooling, the cabin heater going out is normally the cause of the heater coil clogging up, or the blower fan dying out. On the 84 Delta 88s, the cabin air treatment is located under the hood, by the firewall near the passenger. Follow the two large tubes coming from the water pump and radiator to the box itself.

Sorry but it is not a relay. It is a power transistor voltage regulator board located on the center area of the firewall and controlled by the Climate control computor.
