Having an issue with my 15 Escalade. A/C is blowing hot in the front and cold in the rear. Anyone have this issue before? I’ve read it may be a blend door actuator. Any ideas?

I think the same as my Denali. Its in rear on passenger side. its not fun but you can do it. Its a tight fit with your hand. If same as mine it was right below rear window behind big plastic cover.

So the blend door actuator for the front a/c is in the rear of the vehicle? Thought it was under the dash on the front passenger side.

There is one above driver right knee for defrost feet extra. One behind radio kinda on passenger side is for hot/cold on passenger side driver side still works fine if this brakes. There's more up front i think 2 in rear i don't know what exactly they all do but i do know about the ones i have replaced.
And use oem actuator

I broke the steam on the door flap,actuator goes to. Nead to remove dash ac condenser plus more to fix door flap. I glued it and manually move it for heat and ac. If i put actuator on it brakes again. This is the one on passenger side it only controls passenger heat/ac on passenger side. But ac and heat work on driver side.
There's one on passenger side below air bag i Don't know what it does.

Sorry about that the roof vent didn't brake. They blow air just cold when i wanted hot same with back floor vents

I just noticed you have 2015 i have 09 you have new body style. My old style stuff is probably in different places.
But im pretty sure i have 6 heat/ac actuators so you probably have same or more

I'm having this same issue. AC blows cold in the rear (as set), but the front blows hot air out of all the upper vents. Did you ever get a fix...or does anyone else know what causes this?

Today I ran a diagnostic...no codes. Also the AC performed normally. I cycled through all the blower and vent modes, and everything worked just fine. So, this is obviously mechanical, since it does not generate a code...and it is also intermittent. The OP thought it was a "blend door" problem. Can anyone expound on that?
