If the switch controls the roof to open and close then you probably have a short in the wires and they need to be replaced, or you might just pop the switch out and wiggle the wires or if can be taken out of the switch then remove the wire connector blow into it, scrape any gunk you see inside it out, then plug it back in and that could possibly fix your problem

Here's a description the sun roof
Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof module
• Sunroof switch
• Sunroof motor, with 2 hall effect sensors and limit switch
• Sunroof window
• Sunroof sunshade panel
• Power supply for the sunroof module: RAP 25 A
• Ground G402

Override
The override function is used when needing to force a closing of the sunroof window. To override the system:
Turn ignition to ON.
Rotate the sunroof switch to the close position.
Press upward.
The sunroof switch data 6 circuit, or override circuit, will become grounded at the sunroof module. As long as the sunroof module sees this input, it will continue to slide the sunroof window to close, regardless of the other sunroof switch data circuits inputs.

To reset the motor on you sun roof use the switch to fully open and hold the switch for a few seconds in the fully open position then do the same in the closing position. Worth a try.

Moonroof wont close all the way


Do you know how to test automotive electrical circuit's with a DVOM - digital volt ohm meter ? When adjusting the moon roof did you see any switches ? sunroof limit switch
Measure the reference voltage of the sunroof limit switch soft stop signal circuit at the sunroof control harness connector to a good ground.
Does the reference voltage measure near the specified value?
4.5-5.5 V
Notice: Do not open the sunroof glass past the full open soft stop position. Doing so may damage the sunroof assembly and or the roof top.
Connect a jumper wire to the sunroof limit switch soft stop signal circuit at the sunroof control module harness to a good ground.
Turn ON the ignition, with the engine OFF.
Using the sunroof switch, operate the sunroof system, not to exceed the full open soft stop position.
Does the system operate as requested?

Do you know what a wiring diagram is ? Free one's here
http://www.bbbind.com/free_tsb.html Enter vehicle info. year ,make ,model an engine size . Under system click body & accessories ,then under subsystem click on sun roof . Click the search button then the blue link . See the control module , motor an the two switches ? One is probably miss adjusted . or bad !

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof motor with the limit switches
• Sunroof switch
• Sunroof glass-spoiler type, with glass sliding above roof
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power sunroof system circuit breaker: PWR WDO 25 A
• Ground: G204

Sunroof Limit Switches
The sunroof limit switches track the position of the sunroof glass through two limit switches:
• Soft Stop limit switch through the sunroof limit switch soft stop signal circuit
• Vent Stop limit switch through the sunroof limit switch range signal circuit
The sunroof control module monitors the limit switches and based on the input combinations, determines the position of the sunroof glass. As a sunroof limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling the 5 volt reference to 0 volts.
The sunroof control module monitors both sunroof switch input requests and based on the sunroof limit switch input combinations, will control an output to the sunroof motor, to drive the sunroof glass to the requested position.

Sunroof Motor
The sunroof has a bi-directional motor. When the motor is not operating both circuits are grounded. When the motor drives the sunroof glass in the direction from the closed to vent or vent to open position, the following occurs:
• Voltage is supplied to the sunroof motor open circuit.
• Ground is maintained to the sunroof motor close circuit.
When the motor drives the sunroof in the direction from the open to vent or vent to closed position, the following occurs:
• Voltage is supplied to the sunroof motor close circuit.
• Ground is maintained to the sunroof motor open circuit.
The sunroof control module is equipped with a timer circuit which stops the operation of the sunroof motor after 8 seconds.

Where is the manual crank for the sunroof on a 1987 mercedes benz 190E 2.3


In the trunk on the left side is access to the sunroof motor where you can manually close the roof.

I believe it is a 17mm nut. Also I think that the tire lug nut removal tool will fit.
