Question about BMW 325

1 Answer

One side of my sunroof is off its track. I had a repair person disconnect the power to the sunroof so no one would accidentally open it. The repair person also mentioned something about the cables needing adjustment? Help.

    This link was for a 2000 bmw. Are you certain that this is the same sunroof as my 2004 325xi? Also, how do I reconnect the power to the sunroof. A mechanic disconnect the power so no accidental button pushing would occur.
    Thanks

If the repair person is referring into the cable that's connected to the sunroof of your BMW 325, you might want to check the link below. This is for the BMW E46 3-series, but I know this would help:

    Yes you're right, this is for BMW E46 3-series. But most of BMWs have the same sunroof mechanism. You may refer to the link provided and I know that the pictures would help you fix the problem.



    With regard to the power cable that the repair tech disconnected, you might want to contact the repair person to reconnect that power cable because I'm not sure how did he disconnect the power cable and I don't know where did he disconnected it from.



    Thank you!

Wifes sunroof is open and will not close. Checked fuse it has pwr, removed switch it does not have power ... a ground problem at the sunroof motor...where is that?


First off this is controlled by a module (computer) The switch would only have five volts . 5volt reference voltage from the control module . Not knowing how to test the electrical circuit's for this could be expensive . Short out the module or 5 volt ref. voltage circuit inside the module.
Your best bet , take it to a qualified repair shop . Look at a wiring diagram here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on body & accessories ,then under subsystem click sun roof . Then click search button then the blue link . Now tell me you under stand what's happening here .

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof Opening Position Switch (SOPS)
• Sunroof switch
• Sunroof motor/actuator
• Sunroof glass (spoiler type, with glass sliding above roof)
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power supply for the sunroof control module: SUNROOF 20 A fuse
• Ground from G302

Sunroof Opening Position Switch (SOPS)
The SOPS tracks the position of the glass through 2 limit switches:
• Soft stop limit
• Vent limit
The sunroof control module monitors the limit switches and based on the inputs determines the position of the sunroof glass. As a limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling down the 5 volt reference to 0 volts.
The sunroof control module understands the position of the sunroof glass based on the different input combinations through the sunroof limit switch soft stop signal and sunroof limit switch open vent signal circuits.

Power Sunroof Does Not Close
Perform the Initialization/Teach Process any time a new sunroof motor actuator is installed in the vehicle or any time an existing sunroof motor actuator is removed from the vehicle. Refer to Sunroof Motor/Actuator Initialization/Teach Process .

You mean GMC not Chevy ! Chevy doesn't make the Envoy . There is no way to manually close the sunroof !
Power Sunroof Inoperative
If voltage is not measured on the sunroof switch open signal or sunroof switch close signal circuits, the fault could be in the retained accessory power (RAP) supply voltage circuit, battery positive voltage circuit, or sunroof motor ground circuit. If the sunroof motor is not being powered, neither will the sunroof switch signal circuits.

In a 1999 buick regal ls, do I have to remove the headliner to replace the sunroof switch?


No you don't need to remove the head liner to replace the switch . Here are the factory service repair manual directions .
Grasp the switch on the left and right sides. Use a small flat-bladed tool in order to disengage the clips which are located at the front and rear of the switch. Hold the flat-bladed tool parallel to the roof and push straight in. Rotate the switch toward the left side to disengage it from the mounting bracket and pull down. Disconnect the electrical connector from the switch. Remove the switch from the vehicle. This switch is supplied 5 volts from the sunroof module on the brown an orange wires ,the dark blue wire is grounded inside the sunroof module . The switch is just a low voltage input to the sunroof control module , The control module opens or closes the sunroof by the inputs from the switch . The odds the switch being bad are astronomical , more then likely the motor or the sunroof module are bad.
Your best bet would be to have a qualified repair shop diagnose the problem for you ! Do your power windows work ? Sun roof is powered by a circuit breaker an the windows are powered by the same circuit breaker .

My sunroof will not open. It will pop up and down but will not slide back. Someone told me there is a fuse for the sunroof, but I cannot find one.


if it pops open then its not a fuse,its getting power if it pops open, the common problem with these maximas is that the retract arm that opens sunroof breaks and the only way to repair this is to replace the sunroof track.

The sunroof in my 99 bonneville is making a loud noise when i open or close it almost sounds like the motor may be going bad or gears are stripped and i know nothing about sunroofs can you help ?!?


The sunroof motor is located under the roof liner above the center of the rear seat. You will need to remove the headliner in order to access the motor and or track. Do you feel you're mechanically inclind to remove all electrical, sunvisors, side roof handles side trim etc. If not than repairing the motor or track maybe beyond your scope of work. If you are let us know and once done you can proceed to the next step.

My sunroof will not close. I can hear the noise


It sounds like the switch has gone bad or that there is something wrong with the track. If you look on the inside of the sun roof you should be able to see four screws. These screws hold the sunroof in place and to the track. Take those screws out and then the glass. If you look down where the track is when the glass is out and push the button to open and close you should be able to see the track move. If you cant see it move when it is supposed to open pull the switch and see if you are getting power to the open and close side of the switch.

2003 tiburon power sunroof won't close all the way . It'll open all the way but starts to close & then stops.


sounds like the metal deflector in front of the sunroof,is separated and caught in the roof mechanism, however there are other issues that can cause that condition, it can be anything from a bad sunroof switch to the sunroof tracks jamming, start with looking to see if there any obstuctions in the track..the sunroof mechanism can get costly to repair.

97 Grand Prix sunroof off track


My 97 Grand Prix sunroof tracks are offset. My driver side track is in the closed position, and the passenger side track is in a half open position. When the problem happened I was closing the roof and heard a hard clicking. It stopped working from that moment on. The tracks werent offset as much as they are now before I took the glass off. When I removed the glass, the passenger side track sprung back about 6 inches. The motor works, but the tracks only move about a half inch forward and backwards. Its cable operated and my guess is that one side jumped the track or a gear or something. Anybody help?

My sunroof has opened and now it won't close. Any clues?


You will have to remove the sunroof motor, and the sunroof glass. Then you can move the guide tracks seperately until they are in the closed position. Then you can put the glass and motor back in, remove the power source (fuse or disconnect wire harness) to prevent any accidental opening until you can get it fixed. Chances are that a guide track or cable is broken, this can be a costly fix. Do not take it to the dealership, they will only want to install a whole sunroof unit. Take it to a local shop that installs aftermarket sunroofs
