Okay my 95 accord SOHC non vtech 4 cyl has not been blowing out warm air. i checked the waterpump and its fine, i checked the thermostat and it is fine as well (it will warm up and never go down while driving it will stay at good operating temp) also i checked the heater controll valve and it opens and closes fine. i even took it out and checked it and it looks fine.

also if i turn the temp **** all the way to cold and then move it to hot it will blow out warm air for 1-5 min. then go semi warm again.

i am out of ideas please help

Look under the dash on the right side of the console where the carpet meets the firewall and make sure that the bellcrank that the temp **** is actuating is moving all the way . Sometimes the temp **** gets stripped out and only partialy closes the air mixture door.

 

If this is not the problem, I would disconnect the inlet and outlet from the heater core and run water through it with a hose to check the flow. If it seems restricted, alternate the water hose from the inlet to the outlet, back and forth with good pressure until it breaks loose.

 

listen to the ***. he has it right.
