i got this 1990 4runner in january, the heater is always on hot. this wasnt a problem all winter, but now that spring is here, well you know. the controls seem to work and the cold setting is cooler than hot, but still too warm for comfort. any suggestions?

Your thread title cracked me up when I first read it.

I'm assuming it doesn't have A/C?

it does have a/c, but the guy said it doesn't work and being winter i never tried it.

Fink

If that's the case and you have the A/C on and it's still blowing warm air it sounds like you could use a recharge.

thanks i'll check the a/c, what about the radiator cap? read somewhere i should have 9lb cap and mine is 13lb so it runs hotter as it doesnt blow any off intooverflow. but it still doesnt overheat

Did you ever find the cause of your heater always being on? I have the same problem on the same year 4runner - the heater's always on. I've changed the heater control valve, but that made no difference. It still blows warm even when switched all the way to cold, and it blows hot when all the way to hot.

If you did figure out what was wrong, I'd love to know.

All the best,
