Quality, fast shipping, and great price
Works perfectly! I am always skeptical about automotive parts online... Don't be with this, fixed the issue of losing air conditioner and recirculate in 2017 GMC Acadia limited.

Worked on 2015 Acadia
Worked on a 2016 Acadia. Temp gauge was previously reading zero and AC wasn't working as a result. This solved the issue. 10 min repair.

Exact Fit Genuine GM part!
Exact fit Genuine GM part. Even for a rookie this was a simple part to replace. Get a 19mm Deep Socket and it’s so easy to remove and replace. Use a pick to unlock the wiring harness (hardest part) and it won’t take more than than 30 mins. Also disconnect the negative terminal on the battery and the codes should clear. You’ll save a ton DIY vs a dealer. Watch a video to see where it’s at - just left if Dipstick on my Acadia. It’s Easy!!
