Sunroof won't open, when I hit the close button it just clicks

Hi.
I was having trouble with my sun roof on a 2004 Montecarlo. I had two issues water coming in and would not operate fully. I could toggle the switch and it would not move very far. this is what I found. I started to pull down the lining and saw that the motor was in front of the sun roof.
I found the drain lines on the front side corners of the tray around the inside of the sun roof. I found that the tube ran down the pillar's and out between the door hinge's. I took them off and blow them out one was plugged up. That fixed the water problem. The roof would move with help from me pushing. I got it opened and noticed the grease was hard. I cleaned up the grease and removed most of it with WD40.
Now the sun roof works good as new.
I thought the water problem was because the roof was not fully closed but I guess it is designed to have water pass by the roof seal and have it drain away. I always noticed water under the car after a rain or a car wash but did not realize iit was the sun roof draining.

On my 2004 Sebring 4 dr sedan under the front of headliner is the motor for sun roof it has a slot for a metric allen wrench. You can manually crank sun roof closed. Last week I had to do this to my car.

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.

caution if it opens you may not be able to close it again, this sounds like the track broke or something in the motor. lets hope its the motor as if its the track then the whole track needs to be replaced, there is no repairing a broken sunroof track.

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

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.

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.

my apologies for delay in getting back to you.only just sorted this.turned out was the little control unit for sun roof causing problem.it is cable tied to the sun roof frame beside the sun roof motor and can only get at it by dropping the head cloth on one side.learned from a hyundi dealer the switches give a lot of bother,now and again the control units do too.many thanks.

sounds like your sun roofs gear or track is stripped. Replace the motor for the side window had the same problem there really cheap.

some of the cable operated sun roofs stretch making the timing of it out of wack, id drop the headliner and watch for any odd movements while it is closing.....
