Whas up guys. Gonna try to see if I can figure out if one of the blend doors is stick open when the sun come back out out this week. I attached a picture of the 4 blend door a motors. Can someone tell me exactly which one controls the heat by not bypassing the heater core ? I think it’s number 4 but wanna be sure. Thx for any info.

 

Yes, Item #4 is the temp blend door. That should be what you are after. If you remove the glove box, you can see the end of the shaft sticking out of the actuator. make sure that the shaft is turning. There was a problem wit hthe shafts slipping on the actuators.
