Instrument cluster does not work except oil pressure and voltage

Instrument cluster repair or replace . 2003 to 2006 GM had faulty stepper motor's in the instrument cluster . Radio is also probably no good . Checking power an ground connection's for the radio an hooking up a scanner
Battery positive voltage is provided to the radio from RADIO AMP fuse in the fuse block - right instrument panel (I/P). The radio is grounded to G201. The radio is enabled/disabled by class 2 messages from the body control module (BCM). The BCM also allows for retained accessory power which allows the radio to operate for up to 10 minutes after the ignition is turned off. The radio can only be deactivated by one of the following conditions:

NO , there is not a fuse just for those two thing's ! There are two power supply's for the whole insturment cluster . You could need a new cluster or the ECM isn't sending this info. to the cluster . Could have DTC'S - diagnostic trouble codes stored in the PCM or the insturment cluster . Without knowing how this works (insturment cluster gets it's info.) Your best bet , take it to a qualified repair shop that has the knowledge and test equipment to diagnose this problem.
Engine Oil Pressure Gage
The instrument panel cluster (IPC) displays the engine oil pressure as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 psi (0 kPa) or below if:
• The ECM detects a malfunction in the engine oil pressure sensor circuit.
• The IPC detects a loss of serial data communications with the ECM.
For the 4.2L LL8, the ECM uses an engine oil switch that is open when the oil pressure is normal and closed when the oil pressure is low. At normal pressure, the engine oil pressure gage will display 275 kPa (40 psi). At low pressure, the gage will go to 0 kPa and the low pressure warning will be displayed in the driver information center (DIC). At high pressure, the gage will display 551 kPa (80 psi). Any values between these three values are calculated values determined by the ECM.

Voltmeter
The instrument panel cluster (IPC) displays the vehicle voltage based on the information from the body control module (BCM). The IPC uses the serial data information from the BCM to provide a voltage level indication on the voltmeter.

Install a scan tool.
Turn the ignition ON, with the engine OFF.
With the scan tool, perform the instrument panel cluster (IPC) gauges output control.
Does the volt gauge move up and down when commanded?

What is year--make--model?
Sometimes the instrument cluster has to be programmed to the vehicle?
If the voltage regulator is part of the cluster, I'd say you need it.

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:

possibly faulty instrument cluster, also can faulty oil sender, instrument cluster is most common problem for this case, it's some time oil presser sender also create the same problem, need to be check first both of them, first check the oil sender if it's OK faulty instrument cluster, get repair instrument cluster, is this information helped you?

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great.How to guide for Trailblazer instrument cluster repair

What car is this on. There is NOT a BCM in a 2001 chevy s10 blazer.

The stepping motors in the gauges go bad. Do a search on ebay for CHEVY SILVERADO INSTRUMENT CLUSTER for cheaper repair options, dealer costs $300.00
