I don't think the fuse is blown, but at first I couldn't open the sunroof from a fully closed position, then I pressed the button in to make it go up, and it got stuck in the back cracked up position. Any ideas?

PINPOINT TEST E: THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE IN VENT POSITION
CONDITIONS DETAILS/RESULTS/ACTIONS
E1 CHECK THE ROOF OPENING PANEL OPEN/CLOSE OPERATION


Depress the roof opening panel switch rearward and then forward.


Did the roof opening panel open and close?
Yes
GO to E2 .

No
GO to Pinpoint Test D .
E2 CHECK THE ROOF OPENING PANEL VENT UP OPERATION


Make sure the roof opening panel is in the flush position.
Depress the roof opening panel switch up to the vent position.


Did the roof opening panel vent up?
Yes
VERIFY the symptom. Circuit 33-AG10 (YE/BU) is used for close and vent down operation. If the roof opening panel is still inoperative in the vent down position, CHECK for loose connections, a binding roof opening panel track, a sticking switch or intermittent operation of the roof opening panel control module.

No
GO to E3 .
E3 CHECK THE ROOF OPENING PANEL EXPRESS OPERATION
Depress the roof opening panel switch rearward to the second detent position and release.


Did the roof opening panel express operation work correctly?
Yes
INSTALL a new roof opening panel switch. REFER to Switch—Roof Opening Panel . TEST the system for normal operation.

No
GO to E4 .
E4 CHECK FOR REFERENCE VOLTAGE TO THE ROOF OPENING PANEL SWITCH




Roof Opening Panel Switch C912




Measure the voltage between roof opening panel switch C912 pin 4, circuit 32-AG12 (WH/GN), harness side and ground.


Is the voltage approximately 5 volts?
Yes
GO to E7 .

No
GO to E5 .
E5 CHECK CIRCUIT 32-AG12 (WH/GN) FOR AN OPEN




Roof Opening Panel Module C921a


Measure the resistance between roof opening panel control module C921a pin 7, circuit 32-AG12 (WH/GN), harness side and roof opening panel switch C912 pin 4, circuit 32-AG12 (WH/GN), harness side.


Is the resistance less than 5 ohms?
Yes
GO to E6 .

No
REPAIR the circuit. TEST the system for normal operation.
E6 CHECK CIRCUIT 32-AG12 (WH/GN) FOR A SHORT TO GROUND

Measure the resistance between roof opening panel control module C921a pin 7, circuit 32-AG12 (WH/GN), harness side and ground.


Is the resistance greater than 10,000 ohms?
Yes
INSTALL a new roof opening panel control module. REFER to Module—Roof Opening Panel Control . TEST the system for normal operation.

No
REPAIR the circuit. TEST the system for normal operation.
E7 CHECK THE INPUT TO THE ROOF OPENING PANEL CONTROL MODULE


Roof Opening Panel Switch C912



Roof Opening Panel Control Module C921a


Measure the resistance between roof opening panel control module C921a pin 7, circuit 32-AG12 (WH/GN), harness side and roof opening panel control module C921a pin 8, circuit 9-AG7 (BU/RD), harness side.
Depress the roof opening panel switch to the VENT position.


Is the resistance less than 5 ohms?
Yes
INSTALL a new roof opening panel control module. REFER to Module—Roof Opening Panel Control . TEST the system for normal operation.

No
INSTALL a new roof opening panel switch. REFER to Switch—Roof Opening Panel . TEST the system for normal operation.

I have been through two intermittant issues with my sunroof. I could have sworn it was the switch each time. Nope. Took a new motor each time. What a major PIA.....

Turned out to be something with the wiring near the motor and something with the track, I didn't bother messing with it...took it to the dealership.
