i just replaced my heater control valve and my heat is still not working. i have fan motor bypassed with a switched 12v so i can turn it on cuz my factory control box would not turn it on but everything else on control box worked now with heat on full blast i get no heat only cold air. i would love to get my hands on a wireing diagram for he heat and air system for my 1987 toyota supra if anyone has one.
