J-42220 Universal 12V Leak Detection Lamp

Note
Use ONLY the J-42220 Universal 12V Leak Detection Lamp to inspect the sunroof rear window seal for proper application of adhesion promoter. DO NOT remove the rear window from the sunroof assembly. Perform this inspection from the roof of the vehicle with the window in the OPEN position. If the J-42220 Universal 12V Leak Detection Lamp is not available, refer to Seal Push Test in this inspection.

1. With the window in the OPEN position, use the J-42220 Universal 12V Leak Detection Lamp (black light) to inspect the sunroof rear window.





Note
There is no seal or promoter applied to the rear frame (1) of the sunroof window. Promoter will only be visible at the front and both sides of the glass panel, as designated by the green line in the graphic above.

2. Only inspect the sunroof rear window, and only inspect the window at the front edge and two sides.

Note
Results are better seen in lower ambient light. If testing is being done in bright light, use an umbrella, or similar item, to cover the area. The distance the light should be held away from the panel will vary based on the power of the light.

3. Shine the black light along the front and side seal areas of the glass panel, to determine if the promoter is present.





- If adhesion promoter has been applied to the glass panel, a bright fluorescent blue line about the width of line drawn with a pen will be visible along the edge between the seal and the glass. Refer to the illustration. When promoter is found to be present, the vehicle can be released for sale or delivery.





Note
Visible spots of blue color can sometimes be dust, which can be wiped off with a towel.

- If no/minimal adhesion promoter has been applied, no bright fluorescent blue line, or possibly only small traces (1) of the blue color will be visible. When promoter is NOT found to be present, the vehicle must be held and repaired prior to delivery. Place a notification in the vehicle that the vehicle is to be held until parts are available for repair. If the vehicle must be stored outside until the repair procedure is available, make sure the vehicle is parked on a level surface and do not wash the vehicle using pressurized water on or near the sunroof.

Seal Push Test





Note
Perform this inspection from the roof of the vehicle with the window in the CLOSED position.

1. Inspect the sunroof rear window (1) at the front edge and two sides.
2. Locate the sunroof rear window seal (2).
3. Using your thumb, apply a light downward pressure on the rear window seal at the left or right corner of the rear window.

- If the rear window seal does not separate from the window, the vehicle can be released for sale or delivery.
- If the rear window seal separates from the window, no promoter is present and the vehicle must be held and repaired prior to delivery. Place a notification in the vehicle that the vehicle is to be held until parts are available for repair. If the vehicle must be stored outside until the repair procedure is available, make sure the vehicle is parked on a level surface and do not wash the vehicle using pressurized water on or near the sunroof.
