Heater
My heater only blows cold to warm air. Never gets hot. I replaced thermostat. Flushed radiator put new antifreeze in. No leaks. what else is there to check. Its a 1990 Mazda DX626 2.2L 4 banger no turbo. If it has a heater control valve tell me where it is or where it should be. Thanks!

It might not have one. The blend door under the dash could be the problem. Sometimes pens and the such fall in the vents and cause door problems

I put some cardboard in front of radiator and guess what? Heater and defroster getting hot air again. So what do you think know?

also I drove it home from work about 15 mi. or so and there was no pressure on the radiator cap when I opened it while car was running. I replaced that as well when I replaced thermostat.
