Intermittent Heat/Cool Rear Blower - 2017 Yukon - SOLVED

Seth W · Apr 1, 2025

Hi All. New to the forum, and glad to have found it.
I have a 2017 Yukon, and the rear heat/air conditioner blower is working only intermittently. No issues with front blower. Tried replacing fuse for rear below - didn't help. Just ordered a new blower and blower resistor. Any other recommendations as to why the rear blower might only work intermittently? Thanks!

You may want to check the wiring to it. Back seat stuff can get pretty beat up by unsuspecting feet under your seat or some of the junk we put in our center consoles. Or, it might just be giving you both a warning and a blessing. Warning says I’m tired but blessing says I’ll keep working as long as I can to keep back seaters warm or cool as long as I can.

If your Yukon has auto HVAC is the rear system in auto mode?

New blower and blower resistor seems to have solved the problem. Thanks everyone!
