2007 Impala 3.5 no heat

try pulling the hvac fuse inside car it may reset the actuator otherwise the actuator may be bad which you would need to check for power there. there are two one for lh and rh . rh pictured. if no power scan for codes.

Ok update... Upper rad hose is at around 125* lower hose is at 54*. Heater hose is 141* and 145*. Car temp is half way up and been running for about 20 mins

if it doens'tget any warmer change your thermostat

Changed the tstat and still no heat

then check what I said in first reply

You were correct it was the rh air actuator. Thank you so much

Hello HMAC300. Ok I'm not getting full heat. When I installed the new actuator I had to manually adjust the door or the actuator would slide on l I don't know if the door is fully opening or what. Do I need to reprogram the actuator or reset it or what? Thank you

Forgot to add this is a single zone so there is only 1 actuator

check to see if door is broken it may not be working right, take the actuator off to do this.

When the actuator is off the door turns with some force so it doesn't seem like it's broken. I've read some places you need to re calibrate the new actuator with the tech 2

pulling the hvac fuse inside car with key on and leaving it out for 60 seconds resets all actuators
