No Heat

My 86 Fiero does not produce any heat. Any ideas??

replace your thermostat

It could be a bad thermostat, plugged heater core, or the servo isn't opening the flap that lets air into the heater core.

Also check to see if someone by passed the heater core. Two coolent lines going into the right side of the front "fire" wall (heater core inlet and outlet). Some in warmer climates , when the heater core starts leaking, just remove the lines from the heater core and connect the two lines into a loop.

While you are at it, check the condition of the antifreeze: 50/50 mix.
