I am assuming you have a 3.5 you never gave size of engine. See pictures for instructions then when finished pull HVAC fuse inside car for sixty seconds with key on so actuators will reset.

Which HVAC fuse. And with car running or just key on? I tried pulling all four of the fuses on the inside panel. It is blowing out semi-warm heat but not hot. The far left that was warmer than the others. Also when I turn car off blower keeps running. I have to turn heater off then restart car and turn ignition back off for it to stop.

The fuse is in the body control module which is located beneath center console. See if the actuator in picture is getting power if it is then it may be bad. If not it will need to be scanned for codes.

I'm sorry I sent the wrong pic to many things going through my mind. It's by the blower so you will need to remove panel below blower
