Customer Question
After sending the car...

After sending the car out for diagnostic check, my miata heater blows cold and the radiator is full.

Mechanic's Assistant: Have you checked to make sure the thermostat is working? What about the coolant level?

Coolant is full and I'd like to check the thermostat last because I replaced it last year. I believe that it's possible the machanic bumped something to cause a disconnect maybe?

Mechanic's Assistant: What year is your Miata?

2000

Mechanic's Assistant: Are you fixing your Miata yourself? What have you tried so far?

Only checked the antifreeze

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Is there a fuse fo?r the heater control valve

Hi, My name is Jay

You have all manual a/c and heater controls. If you have a warmed up engine with temperature in normal range do you get a temperature change when you turn temperature from cold to hot? Can you hear the temperature blend door moving when knob is turned back and forth?
