Remove the HVAC/ECAS fuse for a minimum of 10 seconds .
Install the HVAC/ECAS fuse.
Start the vehicle.
Wait 40 seconds for the HVAC control module to self-calibrate.
If the System does no Calibrate, then you need to have Dealer Scan Tool check System as it sounds like a Air Door Acuator is not adjusting the Air Door
Wouldn't that basically have the same effect as disconnecting the negative battery lead?
If not, I see 2 fuses listed as "Climate Controls (Battery)" and "Climate Controls (Ignition), Would these be the right ones?
No, as disconnecting the Battery does not reset.
Is this Automatic Climate Control or Manual??
Should be fuse 38 underhood fuse panel
Did the trick!
Thanks Lurch... Appreciate the help!
THANK YOUThanks for using J/A
May have spoke too soon... Back to cold & erratic this morning.
Scan tool time?
Sorry to hear that, sounds like one of the Actuators is sticking or the Blend Door is.Use of Scan Tool will be better than taking Dash apart to look, as that is a pain
