The Problem: The buttons on the Instrument Panel Cluster [IPC] have stopped working.
These buttons are affected:
- 'Fuel Gauge' - the one that shows the 1/4 tank range
- 'Trip Reset'
If you check you should also find that the cruise control has stopped working as well.
The Solution: Replace the 'Cruise Control Fuse, fuse #8, in the center console hidden fuse block.
Information about the center console hidden fuse block can be found here.
This information is not very well documented in the Field Service Manual.
