heat stopped

Hi, last night the heater on my 93 t/c was working and this morning just cool air no heat. It is getting that time of year here in Mich. so... any ideas.

have you checked the coolant/antifreeze level?
if that is low or empty you will have no heat.

I think that i fixed the heater problem, I read that the "automatic" setting is alternating the cool air and the heater. So i guess that i will not be using the Automatic switch until it is warm again.

see about the temperature blend door being stuck only allowing air from the evaporator. it could also just be a fuse depending on what cliamte control system you have (ie electronic climate control)
