Well the problem is that they do not have fan belts. You were looking at the wrong car.
move it to a heated garage, or get a block heater.
Yes some had a gasoline burning heater in the trunk . The rest used the heated air around the engine to heat the interior.
The heat for the interior of your car comes from the heated radiator coolant. When you are driving down the road the water pump circulates the heated engine coolant. If the engine slows and the water pump isn't real efficient you might get cooling in the heater. When you turn off the engine you aren't getting warm water pumped into the heater.
Same way the heater on your truck works... coolant is run through the engine system, becomes heated, is run through a heater coil, and a blower blows the heated air around the heater coil through the ductwork to heat up the vehicle.
if you see no plug than it has neither one you have to pop out the frost plug and put in a block heater
A very common cause for heated seats not working is that the heater element has burned out on either the cushion heater element or the seat back element. The way the system is wired, if one goes bad, neither will work.- techJK ----------------------------------------------------------
sounds like your coolant lines, heater core, or both needs replaced. i just replaced the heater core in my truck with the same problem
Check to insure that the engine coolant is full and the thermostat is not stuck. Without the heated fluid from the engine the heater will always blow cold air.
It's probably not getting heated coolant to the radiator. Check the heater control valve and the control on the dasboard.
There is a failure in the oxygen sensor heater.
Try an engine heater or an oil heater. These are both inexpensive.
If your heater core is LEAKING engine coolant so that your engine coolant level drops too low or the engine coolant is lost completely and causes your engine to overheat then your engine can be damaged beside the mess the leaking coolant makes inside your vehicle ( you might be able to just temporarily bypass the heater core so that no engine coolant is flowing through the heater core )
