98 Pontiac sunfire sunroof will not close.Switch clicks in open but no sound when pushed to close


More than likely you have a defective electric sun roof drive motor. remove the cover on the motor and tap it with hammer handle, if it starts working you need to replace it.

The sunroof will not completely close. There is at least an inch or more gap when the sunroof motor stops. It is causing water to get inside the car.


The motor runs cables to open and close the sun roof. It's called the regulator. it is bad. try helping it to close untill you can have it repaired.

I have water getting inside when it rains on the back floor its a 2002 pontiac bonneville is ther any way to fix it when i go to car wash it leaks in


I'm assuming the vehicle has a sunroof, if so you'll need to be sure there are no obstructions like leaves or small sticks keeping the sunroof from completely closing. If the sunroof is closing properly it may be time to replace the weather stripping seal around the sunroof to get the leak stopped. Please rate this answer, thanks.

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.

Leak!


There should be a rubber lining around the sunroof. That might need to be replaced, if not pull it almost completly off (dont pull it off all the way because its not fun to realign). Go to Lowes and pick up some clear sefl squeeze bathroom caulk and inject it inside the rubber fold.Then reapply. This actually worked on my buddies sunroof.

You are going to have to tear it apart, chances are something in the operating mechanism is broken and until that is fixed you are stuck.
