so i've finally found some time to work on the zed and get it back on the road. when i replaced the heater core eons ago, after putting the dash back in i discovered it only blows cool air out the dash vents. i'm getting the all clear from the diagnostic tests, and i have a feeling i didn't put the heater box back together properly. does anyone have a picture of the heaterbox fully assembled? with all the controls rods and such in their proper place?
