Fuse box, bonnet and wing very hot after short trip

most merc fuse boxes are under the bonnet if your sitting in it its the right hand side also there are relays and a few fuses in the boot

check the gear box fluid levels this is usually the cause of most merc faults on the box

In my c class you open the bonnet next to the light lence where the lights for the front goes at the side of this is a plastic clip if you push it slightley to the side it will come out they come out easier than they go back in if its the small repeater on the wing it just pushes to one side not sure which way and it slots out

Our fuse box info only goes back to the 90's

no the fluid doesn't need to be changed. it most likely is not seeing one of the micro-switches for the convertible top or the windows are not syncronized meaning the one touch/express mode is not working. to sync windows just open and close windows using the 1st detent on the window switch. when the window is fully closed hold switch for 3secs longer. as for the micro-switches the wiring sometimes breaks behind the headliner.

First check that you have oil on the hydraulic pump that it is inside the trunk on the rear right fender the oil should be between the marks. If thats ok check when you put the ignition on if the switch that operates the roof is on, should be off, on means that something is wrong, if blinks 6 times one of the 5 or 7 switchs are not closed, check one by one. check the two that close the trunk at the middle, the cover, the trunk limit switch, the trunk switch

check head gasket. well first run a compression test

Check one of the fuses in the bonnet. There is most likely an electrical contact problem. You will need a fuse wire replacement

there is a sensor in the drivers door that senses the door is locked or unlocked, if the sensor is defective the alarm will sound.

1. Try cleaning the front brake senor.
2. Replace brake switch (under dash).
3. Check front brake pads for wear.
