Review on 🌀 ACDelco GM OE 15-73598 Air Conditioning Vacuum Actuator by Patrick Brinson

Works perfectly! I have a 2004 Trailblazer LS, I6. This drive is responsible for the temperature on the driver's side and for defrosting. Both drives are on the same side. The driver is downstairs and the defroster is upstairs, next to the tower mixer drive. It was easier for me to change all 3 at once. I have yet to swap the passenger side but it still works. I already have a new actuator for the passenger side. The part number is ACDelco 15-73597. Door Tap Actuator (If your air conditioner won't switch from floor to front to defrost. Stuck in one mode) ACDelco part number 15-73596.
