Mercedes slk 3.2 170 PSE problem

[Jammer]

Ok so I've bought a 3.2 slk and the PSE doesn't work.I know there's power to it because when you push the button on the key fob it makes a clicking noise just wondered if there was a fuse for the actual motor that pushes the air through to lock the doors,boot,fuel cap

Any ideas what to check for?

Check the pse pump for water, if the boot seal leaks the water runs down the loom into the pump.

You'll be very lucky if it's just a fuse. Mine had corrosion on some of the plugs. The symptoms for me is that the dash lock button would unlock but no re-lock and the interior light would stay on all the time. Didn't look into repairing it, but got a replacement from a Crossfire which works perfectly.
