I have no hot air coming from the vents in my 90 mustang. Any thoughts? I live in Central Oregon and this car will be undrivable without heat or defrost.
Check your coolant also. I found that if my coolant was low there wouldn't be enough to fill the heater core and it would blow lukewarm air at best. It is most likely the cable though.
I suppose it is slightly warmer then outside. Is there a "schematic" for the heat system? At least that way I can check one thing at a time until I get it going.
could be a faulty thermostat,keeping your motor from reaching operating temperature.Do you have a temperature gauge in your car?If it's not in the operating range,change the the thermostat.
try burping the system, usually if you get an air pocket in the system one of the first signs is no heat. Also is the car getting up to rormal operating temp?
No heat
