'89 Maxima car heater stops blowing warm/hot air

My '89 Maxima stops blowing warm/hot air after driving for approximately 20 minutes. At this time I notice the temperature gauge start to drop to "C". I replaced the thermostat, and water pump but still have the problem. The car does not appear to be leaking any antifreeze and the fluid level is ok. Should I replace the heater value/heater core ?
What should be my next course of action ?

You will have an 'in' and an 'out' hose going to the heater core. Run engine until hot, these two pipe should be both quite hot, if the out pipe feels cooler than the in pipe then it would seem the core is blocked. You say you have no leaks so maybe it would be worth removing both heater pipes, fix one side up to the water main and gently pass water through it. Hopefully lots of Brown sludge should come out.
If both pipes feel hot then the core should be ok. This means it will be an air-distribution fault and maybe the flap is stuck that changes it from hot to cold air.

Heater not blowing hot air


Hi Chris, sounds like your thermostat may be worn and not closing all the way which would cause your engine to run cool at times. If you have a temp gage it should tell you if the engine is actually warming up or not. If not I would replace the thermostat.

always check the coolant first, then feel both heater hoses to see if they are equally hot.
if one hot and one cold, then the heater core is clogged
if both hot then you have a blend door problem.
