I Know my Mode door Actuator is making Noise since last year, However It still moves the air up and down. Now there is a new problem i think there must be another actuator for temp that controls pass side sometime it blows cold but most often hot air. the passenger control lights up and shows blue but only hot air any info would be helpful Thanks

The codes are B0419 and B0429 #2 and #3 what part do i need thanks
======================
Ron already supplied the correct part number -
here is a great HowTo - including pics -

NOTE - when removing the knee bolster - PULL IT STRAIGHT BACK - NOT DOWN -
there are small plastic guide pins that you'll snap off if you tilt it down -

===================

regarding the MODE door actuator -

keep in mind that it moves EVERY time you cycle the ignition -

you already got the ONLY warning of certain impending DOOM -

when it fails - it is stuck in what ever position it was in last -

and you KNOW it's going to fail in the winter - probably on a Monday - during a winter vortex -
when you need the DEFROSTER - but it's stuck on VENT -

the MODE door actuator is ACDELCO 15-72654 - $56 - with free shipping -

here is a HowTo -

we found a few more tips to add - read these -

there are actually 4 -
LEFT/MAIN - ACDELCO 15-72974
RIGHT/REAR - ACDELCO 15-73428
MODE - ACDELCO 15-72654
RECIRCULATE - ACDELCO 15-72974 - yup - same actuator as the LEFT/MAIN -

need the numbers for the one next to the mode door actuator that should be replaced while i'm in there
that would be the LEFT/MAIN - ACDELCO 15-72974 - $59 - with free shipping -
