The sunroof does not close properly. Tried recalibrating but rear edge stays low. Followed instructions from tech service bulletin. (removing fuse 14 procedure) Dealer wants $170 to flash the ecm. Help!
Well, I really screwed this up! I took the advice a bit far. The adjustment holes weren't quite big enough so I took the glass out and enlarged the holes. Now it closes just great! The vent position is good, but the roof won't open more than 1/3 of the way. I guess it's too high to retract. It looks like dealer here I come. I recently installed a new NAV radio which seems to be on the same circuit as the ECM that controls the roof. Doing that must have somehow messed with he roof calibration. A caution for others as lame as me! If anyone has a suggestion on how to avoid the dealer, I'd appreciate it, this is not something to keep me off the road, just another annoyance.

It may be that the glass needs to be adjusted and not the mechanism. Simply close the sunroof and from inside the car loosen the screws that hold the glass to the mechanism slightly and push up on the glass where it is low and tighten the screws while holding glass in position.(the brackets that the screws go through are slotted for this purpose). Open and close sunroof and check to see if it closes right. It may take a few adjustments to get it right. Hope this helps.

Sunroof Description and Operation (One Connector System)
Sunroof
This diagnostic procedure is to be used for the 1 connector Sunroof System that combines the sunroof control module with the sunroof motor/actuator.
The Sunroof System consists of the following components:
• BATT MAIN 2 Fuse 50 A
• Body control module (BCM)
• RAP relay
• S/Roof Fuse 20 A
• Sunroof module (includes sunroof motor/actuator)
• Sunroof switch
The Sunroof System is controlled by the sunroof switch and the sunroof motor/actuator assembly.
When the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the body control module (BCM) applies a ground to the RAP relay in the instrument panel (I/P) fuse block. This activates the RAP relay and allows battery positive voltage to be applied through the SUNROOF Fuse to the sunroof module. Ground for the sunroof module is supplied from G302.
The sunroof can be placed in 3 preset positions:
• Open
• Vent
• Closed
When the sunroof switch is placed in the OPEN position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof motor/actuator then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the full open position.
When the sunroof switch is placed in the VENT position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof module then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the VENT position.
When the sunroof switch is placed and held in the CLOSED position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch close signal circuit. The sunroof module then applies voltage to the sunroof motor close control circuit and applies a ground to the sunroof motor open circuit. The sunroof motor then closes the sunroof.
The sunroof can be placed in any preferred open position when:
• The sunroof is in the fully opened position by pressing and holding the sunroof switch in the CLOSE position until the panel has reached the desired position then release the CLOSE switch in order to stop the sunroof
• The sunroof is opening, it can be stopped by momentarily pressing either side of the switch.
The sunroof control module, sun roof actuator, and the sunroof motor are integral parts of the sunroof module assembly and are not service separately.
Your best bet , take it to a qualified repair shop or buick dealer .
Third attempt...
(new Dell PC: Win10 + old retired XP guy (sorry)).
There is an entire module dedicated to the SUNROOF... ALSO:
There is a pretty good FREE circuit drawing site...
BBB Industries (See below)
(registration required... obviously we are dealing with proprietary information (GM's)... see below... You won't regret it).
There are 25 service bulletins on your '01 Bonneville but NONE
are about the sun-roof...
Going thru the drawing I found FUSE PANEL, REAR
LEAD labelled "A6"... From a 20 Amp FUSE:
Both the fuse and the relay are called "RAF"...
Pulling either will accomplish the switch isolation you seek.
Check the RAP fuse in the rear fuse box , this fuse powers the sunroof control module !
Fuse Block - Rear , Left rear of the passenger compartment, under the rear seat .
The sunroof module contains the logic for the opening and the closing of the sunroof. The sunroof motor assembly contains the reversible DC drive motor, the gear train, and the limit switch.
The sunroof module determines the sunroof motor direction based on inputs received from the overhead console sunroof switches. When the ignition switch is in the ON position or when retained accessory power (RAP) is active, voltage is applied to the sunroof module via the RAP relay. For a description and operation of the RAP system, refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power. The sunroof module controls the sunroof motor direction by changing the polarity of the applied voltage. The sunroof module remembers the sunroof position whenever the ignition switch is turned to the OFF position. The limit switch is used as an input to the sunroof module to indicate that the glass is fully closed, or in the comfort stop positions. The limit switch is grounded when the sunroof glass is in the fully closed or comfort stop positions, otherwise it is open.
The SLIDE CLOSE mode is initiated by moving and holding the sunroof slide switch (ROOF) forward. This applies a ground provided from the sunroof limit switch low reference circuit to the sunroof switch close vent signal input of the sunroof module. The sunroof module controls voltage to the control circuits of the sunroof motor. The sunroof motor will run until the limit switch contacts are closed. The closing of the limit switch will apply the sunroof limit switch low reference circuit to the sunroof limit switch soft stop signal circuit to the sunroof module, indicating the flush closed position has been reached. As the sunroof is approaching the close position the sunroof glass will force the wind deflector downward.
You need to have a factory scan tool hooked up an have it checked for DTC'S in the sunroof control module ! a code reader will not do this , a code reader will only check the engine codes for OBD 2 . Important: The following must be completed before using the symptom tables.
Perform Diagnostic System Check - Power Sunroof in order to verify that all of the following are true:
?€¢
No DTCs are set.
?€¢
The control modules can communicate via the serial data link.
Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation
Probably too late for you, but I just "fixed" the stuck sunroof. I didn't want to spend anything and didn't care if it worked, I only wanted it closed. By taking the motor off, I was able to easily push the sunroof closed, then secured the motor back in place and it keeps the sunroof locked, closed. I tested the seal by running water over it, and all is good. Liquid Roof Coatings Application and Uses BuyLiquidRoof

Some customers may comment on the rear suspension being uneven or sagging.
Correction
DO NOT REPLACE THE COMPRESSOR.
Based on technician feedback, engineering has determined that the customer's concern can be corrected by recalibrating the air spring sensor. Refer to the Trim Height Uneven or Low diagnostics and Air Spring Sensor Calibration procedure found in SI.
The sunroof is powered by the same circuit breaker that power's your power window, so if your windows work than the circuit breaker should be good. You needed test the switch to verify if works with; on the factory sunroof system the roof is controled by a sunroof module the module receives a signal from the switch then throws voltage to the sunroof motor. The motor and module are located between the sunroof assembly and windshield underneath the head liner. You would reconnected the switch and test to see if the sunroof motor is getting power when the switch is in use by testing the dark green wire when closing and a light green wire when opening. Test these wires at the sunroof motor with a ohm meter or test light. Also, check this procedure to repair...
