a/c vacuum control actuator - where to buy?

a/c vacuum control actuator - where to buy?

Postby snailsafari [OP] » July 17th 2020, 9:58pm

1999 GMC Safari AWD

Was poking around under the dash and found this part dangling from a rod. Had to google the part number to figure out what it is since HVAC systems are not my specialty.

GM part number: 52470573
description: ACTUATOR, A/C Vacuum Control

it has a red hose/wire and a blue hose/wire. Seems that in normal operation an arm rotates and pushes down on the plunger presumably to swap air from hot to cold? (red and blue?)
either way, the plunger is definitely not descending since the whole thing cracked off of its bracket. I am more than happy to JBWeld it or something, but also like to know where I can buy this part new as a an option to fall back on.
Google just tells me discontinued at every source I can find.

thanks in advance

Can anyone chime in on this ? Really cannot find it in stock anywhere.

If anyone lives near a u-pull-it I'll pay for part+shipping+time

Update: Found a junked Astro van in a lot nearby and looked inside. Figured out how the thing is supposed to attach and picked up a tube a JB plastic weld. Should hold it over.
