turn fan to on, disconnect fan connection at fan itself. check for power, if power is there. fan is bad. if there is no power it can be a blown fuse, to check if fan is okay, run a wire from fan connection to a 12 volt source, ground other wire if fan is ok it will work! also check fan resistor.

My heater in my 1984 El Dorado Biritz quit working where do you start looking?
If by quit working you mean quit blowing, the things to troubleshoot are the blower motor, the blower motor resistor switch, or the blower motor speed selector switch. If by quit working you mean it only blows cold or warm air, the thermostat is probably stuck in the open position.
If the blower motor quits working after an extended period of time and then afterwards start working again work could the problem be the blower motor resistor?
Could have just overheated
