It appears that someone at GM forgot to install the rear "Pressure Relief Valve" for the drivers side rear cab. It's just in front of the bed on the drivers side. The dealer has ordered the parts twice, but it does not look the same as the right side. My questions is are;

1. Are they both the same on each side?

2. Is there a part besides the vent duct that goes on the inside?

3. Are there any pictures or part numbers you can give so I can get my dealer on track.


Here are some pictures of the location. Missing Pressure Relief Valve PhotosEdited by: Voodoo
