I have read looked around the whole Internet trying figure this out even re-reading re-watching the same videos a dozen time.. I got a chance yesterday to see what the problem was and come to find out the heater core hose that connect to the heater control valve blew out from the firewall. I wonder why everything connected to the heater control valve keep messing up smh lost on what to check... I want to add that my heater inside the car dosnt work as well seem like the climate control just stays on sometime draining my battery to where I need a jump.. the battery is only 3 months old
