Lights on istrument cluster and heat/ac control went out on 2002 1500 silverado ls

STOP and PARK LPS will be tail lights.

ILLUM and GAUGES will.be dash lights.



STOP
Stop/CHMSL, Stoplamps

GAUGES
IP Cluster, DRL Relay, DRL Module, HDLP Switch, Keyless Entry Illumination, Low Coolant Module, CHIME Module, DRAB Module

PARK LPS
License Plate Lamp, Parking Lamps, Taillamps, Front Sidemarkers, Glove Box Ashtray

ILLUM
LP Cluster, HVAC Controls, RR HVAC Controls, IP Switches, Radio Illumination, Door Switch Illumination

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 .

It's not the ground wire , the gauge grounds inside the instrument cluster .Your sending unit or the gauge it's self is bad .
Body Control System Operation
The Body Control Module (BCM) performs the following functions:
?€¢
Gauge control

?€¢
Instrument cluster indicator control

?€¢
Fuel gauge control

?€¢
Temperature gauge control

?€¢
Theft deterrent

?€¢
A/C compressor request

?€¢
A/C cooling fan

?€¢
Exterior and interior lighting control for the following lamps:

-
Daytime Running Lights (DRL)

-
Automatic lighting control

-
Fog lamps

-
Interior lighting

?€¢
Battery rundown

?€¢
Chime

Gauge Control
The Body Control Module (BCM) receives Class 2 serial data messages from the Powertrain Control Module (PCM) to determine the following gauge information:
?€¢
Engine coolant temperature

?€¢
Fuel level sensing

Your best bet is to take your vehicle to a qualified repair shop !
Fuel Gage Inaccurate or Inoperative

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Select the PCM display DTCs function on the scan tool.

Does the scan tool display any DTCs?
--
YES - Go to Diagnostic Trouble Code (DTC) List (2.4L) or Diagnostic Trouble Code (DTC) List (3.4L) in Engine Controls
NO - Go to Step 3

3

With the scan tool, select Instrument Panel Cluster, Special Functions and command the fuel gauge UP.
Does the fuel gauge complete a full sweep when commanded?
--
YES - Go to Step 4
NO - Go to Step 12

1. Turn OFF the ignition.
2. Disconnect the fuel level sender.
3. Connect the J 33431-C Signal Generator and Instrument Panel Tester between the signal circuit of the fuel level sender and the ground circuit of the fuel level sender.
4. Turn ON the ignition, with the engine OFF.
Important: Verify the J 33431-C resistance setting with a DMM.

5. Set the resistance on the J 33431-C to 40 ohms.

Does the fuel gauge display at or below empty?
--
YES - Go to Step 5
NO - Go to Step 6

GM seems to have had poor stepper motors in the early to mid 2000s. Replace with a new cluster or pick one up from the junkyard - beware milage may be programed in the cluster.

Hi William, I'm glad to help!

William, before running after another cluster I'd make certain that the fuse was not blown during the stereo installation. Check all fuses first with a test light just to make sure. Hope this helps and have an awesome day William.

where 2 find d ac fuse

have you checked the fuses?

Hi, this is a pretty common problem on these Silverado instrument clusters. We can repair it for you or provide you with the parts to do it yourself. Click here to learn more about these Silverado instrument cluster problems: Dr Speedometer Instrument Cluster Repair Speedometer Repair Guage...

Hello,

The gauge problems are pretty common on the 03-06 Silverados, it's caused by failing gauge motors inside the instrument cluster. Check this page for more on how to get it fixed - Silverado Instrument Cluster Repair

Thanks,

The LS has several onboard computers that share information on a network. If something on this system shorts or spikes it can cause all kinds of crazy things like this. One of the main culprits for this is ignition coil packs but the coolant control valve has been known to cause these problems also.I suspect that the latter may be the case for you since you only have heat. It mounts to the fan shroud on the passenger side of the car.Try unhooking it and see if this stops the traction control light and parking brake light from coming on.
