Door locks won't lock and trunk won't open
Just went for a drive recently and stopped for gas and the gas door wouldn't open the I noticed that the doors won't lock and the truck doesn't open to get to the vacuum unit which I think is the problem. My manual key doesn't seem to do anything in the trunk when I turn it counter clockwise. How can I get in to the trunk?? Help

Sounds like it could be the PSE pump. To open the trunk turn the key counterclockwise and hold it in that position and pull the lid handle then pull the trunk up. If that doesn't work let us know, you can also try resetting the PSE pump by removing Fuse 71 (Behind passenger seat under the stowage compartment) Also, I know this may sound trivial but do make sure the key is all the way in before you unlock the trunk.

I got the trunk open and removed the PSE pump it appears that that motor has seized up. It does not turn at all that I can tell. The impeller appears to be okay. The motor smells like it has been hot but the fuse is not blown. Before I removed it when I would use the fob it would click like the relay would try to turn it on but motor wouldn't activate. Do I need a new motor only?
