    Another thing that comes to mind is a clogged heater core, or if you have dual HVAC then maybe a blend door actuator is messed up?

    Also, here is a thread I found that may help-> I have no heat! Tried everything...

    thanks for that!
    I have heat but just not the blaring turn down the heat heat and the temp gage is a bit lower than 1/4.
    this morning I decided fun in the cold would be fun! LOLOL
    I flushed the heater core, which seems to have given me back the ,"dam I gotta turn down the heat" back- yay!!
    burped the system again and think I have all the air out... but Ive been told I'm not good at thinking.
    temp gage moved up a bit to just above 1/4 but something I noticed when burping the system:
    I had done some driving so everything was up to temp. cracked the rad cap and there was no pressure. gonna go get a new rad cap and see what happens.
