Defrost/Heat

[no1plantman]

Thermostat is good....heater coil is not leaking, yet I have no defrost or heat. Blower is working as are all fuses. What am I overlooking? Any help or suggestions?

Is your A/C compressor working? I think on most settings the compressor kicks on...for the heat as well as the A/C

A/C comp works like a champ.

Check the heater control valve. It's outside the firewall. Heater hoses run in and out, as well vacuum lines. Make sure the vacuum lines are connected. Feel the hoses that run from the connecter to the heater core. Are they hot?? If they are, then the control valve is probably working, and your problem is the blend door....

If it is the blend door, here is an alternative fix to tearing out the entire dash. Blend door fix
