exactly nubyOz. no burnt fuses.Hi,
I think the info is incorrect. I got a '92 500SEL.
PSE (Under the right rear seat) does Trunk handle, lumbar, AC, central locking, reverse antenna, ...
Closing Assist Pump (in boot, behing passenger seat on left, beside tank) does that: closing assist, nithing else.
Mine is a acting a bit strange, need to close boot always twice, first time it comes up again too much.exactly nubyOz. no burnt fuses.
door assist works as it should, but I heard a burbling under the boot latch near ext lock the day before the pse quit, i guessing vaccum hoses as a possible suspect.
in 92-93 models, the PSE pump (under rear seat) does EVERYTHING, but door closeure (for trunk and 4 doors)Mine is a acting a bit strange, need to close boot always twice, first time it comes up again too much.
Will take my latch apart next few days and post pics.
central locking pump (only one function of more) IS called PSE pump. it is under the rear seats. The another pump (close assist pump) is in the trunk. I can be 100% sure because my car has not any close assist pump at all ... and the trunk handle is working.On 92 models I believe the central locking pump is responsible for the trunk handle not the pse pump in the trunk. It is also responsible for a\c flap in the middle and reverse guides.
The brand-new pse was in my car & failed after only one year. That includes being in climate-controlled storage for six months.I am not sure if I missed something, but did you buy a new pump and take it apart?
