Heater and a/c fuses are in same box. The a/c problem is commonly a lack of refrigerant rather than a blown fuse. There are other posts on this topic.

Heater fan stopped running. Is there a fuse for that and if so where is it located?

My 1994 Japanese XCab has fuses for heater and a/c on the passenger side of the vehicle about where the upper door hinge is. Remove the glove box ... 3 screws across the top and a screw and a bolt below . Fuse box has a cover on it.

Heater has low fan flow and only heats in recirculate.

Apparently you have a coolant leak. Hopefully it's external and not something like a blown head gasket or timing cover that has been eaten by the timing chain. There are dyes to help find external leaks, even a bad radiator cap can cause a problem.

Will a bad IAC valve cause overheating in less than a half hour of run time? 22re.

No. The IAC valve controls the idle of the vehicle, and not the cooling. Most likely has a bad radiator and thermostat. See if running the heater on high heat and high fan brings the temps down. If it does, this is the problem. If not, possibly fan not turning like it should.

I have a 94 toyota pickup 22r engine--the engine revs up and down when ideling and is going thru alot of antifreeze--i live in alaska so its always cold--and now the heater is running cold air here and...

I think the problem is your IAC valve under the throttle plate. What happen is the water passages gets blocked and does heat up the idle air pass through. This procedure is part of regular tune-up according to service manual.

1994 toyota pickup heater stopped working

Sounds like there is air in the cooling system causing the engine not to overheat but the heater not to work. Flush cooling system and work the air out of the system.
