The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

There has been a condition identified with the Panel to Panel latches that might cause the Convertible top to become inoperative. When this condition occurs it may cause the Panel to Panel latches to "Stick" and may even BEND the Panel to Panel link rods.

If you experience this condition please perform the following instructions

1. Remove the front roof panel headliner and check for the header latch and both side panel to panel latch being able to totally unlatch. If they do not unlatch go to Step 2. If they do totally unlatch go to Step 7.
2. Check for possible Left and/or Right bent Panel to Panel latch rod/s.
3. If the rod/s are bent then replace left and/or right side Panel to Panel latch/es (new rods come with the latches)
4. Before installing the Panel to Panel latches check for lube on the latch hinging pivot points to make sure there is no binding.
5. If there is NO lube on the NEW latches, then lubricate NEW latch hinging/pivot points with GM Superlube Spray before installing.
6. Finish installing the latches, rods, adjust properly, test and verify the top operates correctly and then reinstall the headliner.
7. From Step 1. If the latches operate correctly and you have Codes B3683 (S17 - Header Switch) and/or B3685 (S18 - Header Switch) and/or B1296 (S1 - Header Latch Actuator Switch integral to the Cylinder) and/or B1010, check for proper operation of the S17, S18 and S1 switch and circuitry. If the switch/circuit is not operating properly, replace the switch/repair the circuit and retest top for proper operation.
