SOURCE: heater core replacement
This is a really easy job, disconnect the heater hoses at the firewall, go inside the truck on the passenger side there is a plastic panel/cover over the core, 6 bolts/screws I think, remove the cover pull the core, tops 1 hour, as job at work I did them in 20 minutes.

This problem is specific to the Gen4 Celica (86-89). Intermittent or no heat heat is caused by cracked
solder joints in the Heater Control Panel. You need to remove the panel
and re-solder the solder joints. When electrical continuity is broken,
the panel defaults to the cold setting. If you go over a bump and it
touches again, you may get hot. Hence, intermittent or no heat. We have
the complete DIY fix posted at www.st162.net and it's free. Pic below shows the heater control points to re-solder.

The heater core is a small heat exchanger located inside the
truck, similar to the radiator at the front of the truck. Coolant is
circulated from the engine through the heater core and back to the
engine. The heater fan blows fresh, outside air through the heater core;
the air is heated and sent on to the interior of the truck. For Toyota Pick-ups/Land Cruiser/4Runner 1989-1996 check this reference repair guide...

Have alot of towels handy for the leakage of coolant that may spill into your interior.
Hope this help (remember comment and rated this).
