    I had a 93 Toyota truck that didn't have heat either and found out that the thermostat was stuck open so the engine wouldn't heat up so no heat.

    My engine heats up pretty quick according to the temp gauge, so I had ruled that out.

    I had that problem in my 95, I recommend flushing all the coolant out and starting fresh and clean and using a radiator cleaner. Youre gonna back flush the heater core. Google the control heater valve i20190409_131049.jpg f you can't find what it looks like... after you might still have to flush out again. If it keeps clogging might have a rusting issue.
