Fan blows air. no vacuum signal to heater control valve when console switch is set to heater. PO let the car sit for a long time. not sure if this issue is vacuum lines, stuck fan box doors/baffles, or? ![Confused :confused: :confused:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)
160 deg stat plus 20-40 deg air temps isn't going to yield very good hot air. I replaced the heater core a few months ago.
