Difficult to View Instrument Panel Cluster (IPC) Display When Driving Toward Bright Sunshine (Replace Instrument Panel Cluster)
| Subject: | Difficult To View Instrument Panel Cluster (IPC) Display When Driving Toward Bright Sunshine (Replace Instrument Panel Cluster) |
| Models: | 2006-2008 Buick Lucerne |
This bulletin is being revised to add the 2008 model year and provide the part numbers for new IPCs with bolder graphics. Please discard Corporate Bulletin Number 06-08-49-021A (Section 08 -- Body & Accessories).
Condition
Some customers may comment that the Instrument Panel Cluster (IPC) display is difficult to see when driving toward bright sunshine. This condition does not affect the IPC operation.
Cause
This condition may be caused by an insufficient color contrast in the IPC display and to insufficient ambient light reaching the cluster face due to deep tunnels around the IPC gauges.
Correction
Technicians are to install a new IPC with a display that has improved color contrast. To improve contrast, the new instrument clusters listed below all have black appliques/backgrounds. These will be used to replace the instrument with blue appliques/backgrounds. This will be a change to the customer. Refer to the Instrument Cluster Replacement procedure in SI for more information.
