I have an 02 3.0 SOHC that 2 weeks ago decided to stop blowing hot air. If I leave the fan on the lowest setting, it trickles hot air out, turn it up at all and it cools right off. I flushed the radiator and changed the thermostat, same thing. At one point, when I had flush in it, it blew really hot like it used to. But once I finished flushing it out and filled it back up with antifreeze, it just won’t put any heat out. I’ve ran it around with the scan tool hooked up to monitor the coolant temp. It gets up to 200, thermostat opens, cools down to 180 and there it stays, but no hot air. Any ideas?
