The heater does not blow hot. When you adjust the temp. knob on the dash nothing happens. The heater hoses get hot but you get no hot air in car.
I pulled the glove box out and the linkage on the what i believe to be the heater door operator tries to move when you turn the temp. knob. If you help the linkage the least bit it will go ahead and move. Once it moves you can operte the knob slightly and the linkage moves as it should. If you ever turn the knob all the way back to cold then you have to help the linkage move again to get the heater to blow hot air. did not tear down any further. Need advice.
