I had to manualy remove the hard top and manulay raise the soft top. When I use the top switch I hear the motor trying to engage but nothing happens. Can somebody send me some diagnostic info for this system.

Mercedes Soft Top Controller Reset Procedure. R129 1990 thru 12/93.
Locate the diagnostic connector: Under the black plastic cover over the hood-up switch on the US passenger side of vehicle near the strut mount. To recover codes from the soft top controller: Connect a normally open (N.O. S.P.) switch between pin 1 and pin 10. A simple push button switch with leads or a short jumper lead will also work OK. Short (close switch) 2 to 4 seconds to read error codes. The lamp in red (operate) top switch ( in the console ) will flash out a number of pulses. Count the pulses and see the chart. Short (close switch) 6 to 8 seconds to erase error code. There may be multiple codes stored, so read / erase until all are cleared or the problem Is located. Some codes may require reading / resetting twice before they will erase. The codes that will suspend operation of a soft top on the R129 are 21, 22, 26, and 30. A code of "1" indicates no faults and no hard top in place, while a code of "20" indicates no faults and the hard top is assumed to be on the car. 2 = Limit switch, LEFT locked, soft top storage compartment cover. 3 = Limit switch, RIGHT locked, soft top storage compartment cover. 4 = Limit switch LEFT closed, soft top storage compartment. 5 = Limit switch RIGHT closed, soft top storage compartment cover. 6 = Limit switch LEFT locked, soft top fabric bow. 7 = Limit switch RIGHT locked, soft top fabric bow. 8 = Limit switch LEFT closed, soft top fabric bow. 9 = Limit switch RIGHT closed, soft top fabric bow. 10 = Limit switch LEFT front locked, soft top. 11 = Limit switch RIGHT front locked, soft top. 12 = Limit switch soft top storage compartment open. 13 = Limit switch soft top fabric bow raised. 14 = Limit switch soft top down in storage compartment. 15 = Limit switch soft top up ( secondary closing speed ). 16 = roll bar retracted switch. 17 = Left window failed to lower (limit switch open), bad fuse, or window relay on controller. 18 = Right window failed to lower (limit switch open), bad fuse, or window relay on controller 19 = Vehicle speed signal to controller missing or illogical. 20 = Hard top installed, no faults. 21 = Controller module / soft top switch circuit open. 22 = Roll bar switch activated. 23 = roll bar control unit not functioning. 24 = Roll bar crash deployed. 25 = contradicting switch inputs. 27 = insufficient voltage. 28 = Speedometer signal is missing. 29 = Wheel speed from ABS control module missing. 30 = Top operation disabled (due to #29).

what if the light does not blink at all. I found a relay in that area that uses 2,10 amp fuses ... judging from all the carnage (blown fuses) in the area someone has been messin' around in here... I mentioned that I just purchased it ...I don't have any back ground info to give. Anyway, I replaced the fuse and tried to start the diag process,still no blinking., what is next
