Why is my 1993 Cadillac devile heater not blowing heat
Your heater core has gone out. It is located behind the dash board. They can be a real pain to mess with. Good luck!
It could also be your thermostat has stuck on open, not allowing your own r engine to heat up to optimal operating temperatures. This is cheap / easy fix, maybe fortune is with you.
Long list of possibilities but does your fan run?
