GMC Terrain/Chevy Equinox Side Air Bags
Recently we had a 2011 GMC Terrain in our shop to replace the side air bags. They were deployed when a deer hit the front passenger door right at the scensor. The dent was less than 10" across and 3" deep but it was enough to set off the bags.
Our tech had to replace the whole system and while he had the interior apart I had the chance to take these pictures. Please note where the gas cartridge is, over the "B" pillar. This is why it's important to take the time to pull the interior finish if you're not sure.
