Hi,

first I'm new in there and I'm grateful for the forum community.

i have trailblazer 08 that started blowing hot air from passenger side and cold air from passenger side when turning A/C on.:crazy:


i tried all the calibration, battery off but it seems that i need to change the actuator based on research on the forum.

my question is what is the correct OEM part number for the actuator, also are the ac delco 15-73596 and 15-73598 interchangeable?


and just to be sure is it the bottom actuator that is near the radio or the far up in there.

Thanks in advance guys

The temp actuator is the one closest to the driver.

The two part numbers you mention are not interchangeable. The 15-73598 is the Mode actuator.
