I replaced my heater core because I was getting a fogged up windshield which would then freeze It got hot and I had heat before but the coolant on the windshield got real old. Now after replacing the heater I get nothing. By nothing I mean with the controls on "warm" the air doesn't even come out the vents. If put the temperature selector on cool I get air out of any vent I set it to. As i slide up the scale from cool to warm less and less air comes out of the vests (any of them I have it selected to) About half way up toward warm on the selector the air starts to slow then completely stops at about 3/4 the way up towards warm. Do I have the heater hoses to the core on backwards maybe? On the heater tube, the top one goes to the left (smaller tube) and the bottom tube on the intake heater tube goes to the right (larger tube) which is also the one that should have the coolant flow restrictor in it correct??? At no time does the air get even warm....Please help as its getting seriously cold here in Wisconsin and I wont be able to drive it anymore without heat. Thanks
