Load Compartment Cover Drive Does Not Switch Off After Reaching Upper or Lower End Position and Makes an Objectionable Noise





If you receive customer reports in the above model vehicles that the load compartment cover drive does not switch off after reaching the upper or lower end position, it is possible that when the guide rail for the load compartment cover was installed the hose was twisted (Figure 1 incorrect) on the guide sleeve for the helical shaft. In this case, the crimped portion of the clamp for the hose points towards the D-pillar. This prevents the drive pinion from optimally engaging in the helical shaft. When the end position of the load cover is reached, the current draw of the drive motor, which should be high for a brief moment and serves as the signal to de-energize the drive motor, is not generated and the motor then continues to run for an additional 20 seconds. During this 20 second run on period, the owner generally hears an objectionable noise and may report that condition. In this case, it will be necessary to replace the motor and drive assembly for the load compartment cover.

1. Remove guide rails for the load compartment cover on the left and right sides. Refer to WIS Document AR68.30-P-4495T.





2. Check the left and right side guides for damage in the area of the guide sleeve for the helical shaft (Figure 2, circle). Replace damaged guides.

3. Remove drive assembly for the load compartment cover. Refer to WIS Document AR68.50-P-4950T.

4. Reinstall drive assembly for the load compartment cover. Refer to WIS Document AR68.50-P-4950T.

5. Reinstall guide rails for the load compartment cover on the left and right sides. Refer to WIS Document AR68.30-P-4495T.

Note:
Pay particular attention to the position of the crimped portion of the crimped on hose clamp. It must be positioned correctly (Figure 1, correct).
