I am trying to sort out the heat issue in my van 2003 passenger van. At 145 degrees my air is blowing barely warm. I didn't get to 185 degrees because I got busy but should it be hot at 145? I will get my van to temperature later and see if it blows hot but I suspect my thermostat is stuck open because the van takes forever to warm up. I did the hand test on the heater valve and all three hoses to the valve are hot so I think maybe thats not the issue. I get 0-12v on it as well so I know the ATC is probably ok too. I didn't do a test on the pump yet and thats next for me as well as getting the van to running temperature.
