No heat comes out in either the automatic or manual settings of the climate control unit. The climate control unit unit has been recently replaced due to a blacked out LED and it appears to be working properly. Does anyone know the likely cause of this problem?

Has the heater worked at all since the control was replaced? If not, the control is either defective or not hooked up properly. Either way, you'd want to go back to the folks who replaced it to get them to finish the job so that your heater works. (If the heater was working after the control was replaced, then anything in the whole system could be broken. You'd need to say more--does cold air come out of the heater vents, do you let the car warm up first, any peculiar odors, is your thermostat working normally, etc.)

also check to see if the temp. setting is up.
