The instrument cluster may illuminate randomly to its full brightness and/or the fuel gauge may drop to the empty position. Typically the symptoms are infrequent and the instrument cluster returns to normal operation after a few seconds. An update to the body control module (BCM) will fix this problem.

Chrysler Concorde Update to BCM Will Fix Problems With Instrument Cluster/Fuel Gauge
Chrysler Concorde Problem
Average Mileage: 148,333 mi (105,000 mi - 170,000 mi)
Visitor, 2001 Chrysler Concorde, 105,000 mi
been doing this with the heater on since about 45000 miles
Instruments stopped working...even the odometer...blowing the 5 amp fuse labeled "cruise"
I actually experienced this issue by the dashboard lights going from dim to bright and my gas gauge going from full to empty. I had to take the BCM out of the vehicle and have it rebuilt with an online company which took five business days and it was less expensive than buying a new one
