Why do my instrument cluster lights stay on all the time even with truck shutoff.

Replacing a fuel pump has nothing to do with instrument cluster lights or the clock staying on. Unless you shorted wires , did you disconnect the negative battery cable before hand ?
The body control module (BCM) performs the following functions:
• A/C compressor request
• A/C cooling fan
• Exterior and interior lighting control
- Daytime running lights (DRL)
- Automatic lighting control
- Fog lamps
- Interior lighting
• Battery rundown
• Chime
• Gauge control
• Instrument cluster indicator control
• Fuel gauge control
• Temperature gauge control
• Theft deterrent
Interpreting all of the driver warnings sent by the control modules on the class 2 serial data line
Sending the information to the instrument cluster in the form of a SPI serial data bus message
The following list of messages are sent by the BCM to the instrument cluster:
• Fuel gauge position
• Temperature gauge position
• Oil pressure
• Low engine coolant
• Check oil
• Volts
• ABS
• High beam
• Low fuel
• High temperature
• Washer fluid level low
• CRUISE
• BRAKE
• SERVICE VEHICLE SOON
• Door ajar
• Seat belt
• THEFT SYSTEM
• PRNDL
Check the fuel level sensor wires , the fuel level sensor is a input to the BCM .

Pull fuse if its not tied w a crucial component. Or git a the instrument cluster and take out bulb. May hav to break it.

the instrument cluster is failing--they can get exchanged at napa auto or a private shop can take it out----but 1st disconnect batt or computer to see if car clears or reboots-at times this works-but the age of the vehicle is against it

Replaced once before and still periodically happens. Disconnect battery and reconnect and it starts working on our voyager.

one hour job. find bulb part number in bulb chart in owner manual.

Probably too late but I had the same problem yesterday. Try changing your battery. It sounds crazy but it worked for me.

you need a special tool to get the radio out. It has pins that spread out spring clips so the radio can pull out.

please rate as solved if this helps.

hi,seem lighting switch is grounded or wiring for cluster is grounded,if can remove the lighting switch disconnected the wire,see if light in cluster is off,switch or wiring must check,ty

The battery light comes on if the battery voltage is too low. Check you battery voltage. It should be above 12V with the engine running. If not, the alternator is not working. Next, check if there is power on the FIELD terminal of the alternator. Again, you should have 12+V. Check if the Alternator fuse is blown.
