Not sure on the 88 but my guess is there's a resistor bank somewhere that is toast.
Did you have fan speed control issues prior to it going out completely?

NOPE!
If the resister goes it will still blow but only on high. I would double check the fuses and related wiring and the heater control switch and make sure that it or the connections to it haven't melted.

Check fuses for power in and out . Then check dash switch for power.

Electrical portion of the ignition switch probably burned up at the brown wire. switch is located on top of the steering column up under the dash. Refer to the photo already posted.

Never have. I always listen to the vehicle I'm driving. Weird, I know.

I always pictured you in a leisure suit dancing disco to Donna Summer....LOL.
