It got hot last winter but when I tried it this year it will not get hot. Engine temp is running 190 and there is no sign of anything being wrong like leakage from heater coil or anything. Air conditioner works fine and Fan works fine.

    core could be clogged with debris. blend door motor may be bad as well. take it to a shop and have them check it for you and give you a bid.
