Trunk help needed.

So i have a 99 e430 and i recentley locked my keys in my trunk. I got my spare and i soon relized that the trunk release button on the key does not work and the key for the trunk does not fit. Also the trunk release switch next to the center console no longer works. I was wondering if anyone knew the best thing to do in my situation. I'd prefer if some one could tell me what to do to fix the trunk release switch by the center console because i'd think it'd be as easy as fixing a fuse or something along those lines. Thanks

  • go under rear seat.
  • move foam around to reveal PSE pump
  • look for terminal "HECK" (from memory)
  • CAREFULLY !...remove hose from the T fitting.
  • blow into it and watch truck lid rise.

no suggestions simply because any tip would be something I'd feel bad about
if it resulted in a fracture to the T-fitting. hmm, but as i type i had a thought:
  • suppose you first checked to see how much slack you had in that line.
    if you have enough, that could mean that if you damaged the end of
    the hose during removal, you could simply cut it off squarely, then
    just push it back onto the t-fitting.
  • the connectors are splined, somewhat barbed-like
  • you could try *carefully* using a handheld hair dryer on it

in my case, it pulled out with a little twisting, pulling motion without trauma.

with the hose off, you could also have someone press the trunk release button. position the
unplugged end of the hose hear your face/eyelid to see if you can detect puff of air when the
switch is activated. if so, then the pump is working and the malfunctioning part is further
downstream, e.g. a break in the line going to the trunk, a loose hose at another t-fitting
downrange towards the trunk, etc.
