Review on High Quality Gray Control Knob Heater AC for Pontiac (Grand Am 1999-2005 & Grand Prix 1997-2003) - Compatible & Reliable Temperature Switch by Red Hound Auto by David Caldwell

Pretty easy to install. You just need to make sure the broken handle's small hard thin piece of plastic isn't still on the AC stand before attempting to install a new handle. If this small piece is still there, the new pen will NOT work. Red Hound's customer service is excellent. Didn't even think to look for the broken piece that was left behind because it's very difficult to see. New handles work great! Very happy with this purchase.
