    Tahoe 2003 5.3 liter with Auxiliary rear heat controls located in the front overhead ceiling:
    I am having difficulty identifying the correct replacement part for the Auxiliary Rear Temperature Blend Door Actuator.

    Dealer said that the original part number #15201869 is no longer available, and that there have been 3 subsequent changes.
    The latest change listed was PN was ACDelco 15832319 , discontinued.

    Advanced Auto listed Motormite 604-100 as exact fit, $40.
    Ordered it. Installed it.
    My experience was incorrect PIN pattern: Failed .

    Internet shows prices from $20 -$160 for exact fits.
    What part is correct?
