Review on ACDelco GM Original Equipment 15-72972 Temperature Valve Actuator: Reliable Control for Optimal Temperature Regulation by Shahed Cleveland

Revainrating 5 out of 5

Finally no more annoying loud clicking noise under the dashboard

For many years, a loud clicking noise can be heard under the dashboard on the driver's side when the air conditioning is running. After some internet research and listening to clicks, it was determined to be the temperature sensor in my 2002 Trailblazer. It took me a few hours to replace after finding instructions online and now it works like a charm. No more loud annoying clicking while driving. Air conditioning works perfectly. Although I thought this part was quite expensive, I'm glad it was finally fixed without having to pay anyone else for it.

Pros
  • This is amazing
Cons
  • Low maintenance
