Review on 🔥 ACDelco GM Original Equipment 15-74122: High-Performance Heating & Air Conditioning Temperature Valve Actuator by Jay Hill

Bought for a neighbor who told me she had pops/clicks and had trouble switching hot to cold and vice versa. This issue can cause the inner windshield to fog up which reduces visibility so I fixed it as soon as possible. I ordered one for the passenger side and then the driver's side came out. My retrospective is now your 20/20. order two. I think you'll need a 7mm or 8mm socket, a 3" extension, a ratchet or hand tool and small strong flexible hands (it's been 7 months so don't include socket sizes) . The driver and passenger units are identical so you will need to worry about ordering different parts. I saw some other parts that didn't fit in the ACDelco bag, so I can't tell you about the quality of the other parts. and that can say a lot about the durability of the parts i have installed, but on the other hand i would rather replace the part after 5 years than maybe in 5 months.
