As you all can tell i have a great s320.. but i have a problem, with the reverse anntennas and the power locks, the reverse antennas are always up, they never go down, my radio antenna doesnt go up, no power locks, some buttons in my dash do not work, head rest drop, traction button (chains), on the back of the trunk when you press the button, the handle doesnt come out anymore, and the auto pull, or whatever its called when you dont close your door all the way and it closes it for you doesnt work anymore... thats pretty much it for now, im working on sealing the blown head gasket with kw block sealer and replacing the spark plugs, please if you have any suggestions please reply, thanks in advance -S320

 

The pump under the rear passenger seat, controls the locks , head rests (non electric), lumbars, back up rods and handle. It also provides back up vacuum for the HVAC system. I would unplug it wait a few seconds for the memory to clear and plug back in, if it sees a leak or high pressure it will disable it.
The closing assist (pull) in is another pump located over the driver rear wheel try pulling fuse #9 in trunk which should reset it, to get at it remove both the tank liner and wheel liner from tunk you will see it back in there. There may be a common fuse, I dont know, the traction control is seperate issue, and so is the antenna.
