Why isn't the electric roof working?

Some fixya user told me a website reliablestore it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try

check fuses.
check 12vd to motor,
no 12, work back to switch
yes, 12, motor make noise
no, motor dead.
motor make noise yes, the roof guides are jammed.
or motor is weak. remove motor and move roof by hand.
is it jammed?

It will not show up with a typical P code from Autozone. It might show up with a dedicated code reader for specifically BMW. My code reader with BMW extended program does not show it. To trouble shoot this without a BMW code reader, try your buttons first, if you do not hear a motor noise, then you need to check if motor is getting power when button is pressed. Take of access panel in center of roof forward near rear view mirror. You will be able to access the motor there. Probe the electrical connections going to the motor and have someone push the buttons. Review the meter while buttons are pressed to see if motor is getting approx. 12 volts. If so then the motor may be dead. If there is not activity at the motor as far as 12 volts, then you have an electrical supply issue which could be several options: Electrical wiring, loose plug somewhere, a bad fuse (most common), a bad switch (probably not if both switches do not respond to electrical test), or a bad relay. Remember to check the truck are for the roof storage panel. If this is in the up position it will not allow enough roof for roof the store in truck and will not allow roof to move, retract.

it can only be 3 things.
1: no power to motor (12v not there active or is too low)
2: bad motor. 12v there its dead.
3: jammed up track overloading said motor.
a voltmeter solves #1 and 2 in seconds.
leaving.......

The system is operated by hydraulic pressure the pump you hear is the hydraulic pump running, but your fluid has leaked out due to a problem in the lines or the cylinders that lift the top, you have to tear it apart and find the leaking parts.

The first thing to check is the roof is actually secure. Somewhere there will likely be an electrical contact that makes and breaks when the roof is up. This will activate a circuit which will tell the computer the roof is up thus allowing certain operations to be executed (in this case the heated rear window). Over time these sorts of connections can corrode.

there is no manual method. It sounds like a limit switch is not working. Can you hear the motor try to operate? If you push up on the back of the glass a little bit while hitting the switch, what happens.

The sliding roof panel system consists of the following components:

• RH circuit breaker
• Timer module
• Power window relay
• Roof sliding panel switch (15B691)
• Roof glass panel (50054)
• Sliding roof panel motor (15790)
• Halo moulding
• Roof sliding panel headlining (519A02)
• Roof sliding panel slide links (502M78)
• Roof sliding panel housing (502C22)
• Roof air deflector (500A26)
• Center green diode strip

-------------------------------------
When the roof sliding panel switch is activated, a gear on the sliding roof panel motor drives a spline on the roof sliding panel housing. Within the roof sliding panel housing, the spline is connected to two sliding roof panel cables which cause the roof sliding panel slide links to slide and the roof glass panel to open or to close. The sliding roof panel cables and the spline are part of the roof sliding panel housing. Neither the sliding roof panel motor nor the roof sliding panel housing can be disassembled. If a malfunction is detected with either of these assemblies, the assembly must be replaced.

Is your Alternator bad?

Good for you ! Grab yourself a can of electrical cleaner, or contact cleaner & spray that switch good, it may save you another episode in future.

hi,seem only adjustment of micro switch,to detect which switch are need to adj.you need to send to dealer.
