No heat

Hi,

If you lost heat to both at the same time, I suspect the heater core is plugged or you are low on coolant. Also, confirm that the engine is warming up to operating temp. It could be related to a faulty thermostat.

Take a look through this link first and let me know if it helps:

If you get the chance, let me know what you find. Also, let me know if both heater core hoses on the firewall (under the hood) are getting hot when the engine is running and the heater is on.

Take care. I'll watch for your reply.
