!40 trunk assist
I would suggest you try two things, check the (lower) latch for adjustment, mine has come loose before. Close the latch by hand, the one on the body not the lid. The catch should retract like it is pulling the lid down, check to see if it is coming back to its origional position after a few seconds.The sign of a bad pump is to not pull it in at all, maybe the (lid latch) is just binding, and after the vacum is released it has not latched.
