I did a quick search and didn't see much on this topic, so hopefully it is not totally a repeat.
The heat in my car not working properly. It has the electronic automatic control. The fan blows but the air coming out of the vents is not Hot. I would say it is about 10% of the warmth it was last year before I put the car away. I have checked the vacuum line going through the firewall and replaced the heater control in the dash. I believe there is a little vacuum actuated door in there somewhere but not sure where to look. Any ideas on where to look next?
Thanks,

Possibilities:
--Blend door actuator
--Clogged core line
--Stuck thermostat
