Dash lighting on my 2004 chevy avalanche

I would get a replacement loom from a scrap yard/breakers yard and fit that.

Back side of the frame it says.

Get dat alternator checked...autozone r somewhere. U can even buy a lil adapter dat plugs into ya cigarette lighter dat will check ya battery and alternator

I would want to know what the actual oil pressure is. The sending unit or the gauge on the dash could have failed.
There is a pressure relief valve to prevent oil pressure from going too high, but staying at 80psi would not be good for a long time.

Different car has different way to reset. Read its manual, it should tell how to reset.

mai

need scanner light comes on for reason thats what the codes are for they help see whats caused the fault to turn on light
and it can be anything loose gas cap bad o2 sensor missfire
90% is loose gas cap rule of thumb if the way it drives does not change dont panic, if engine shakes n shudders get checked quick
if fuel mileage is suffering get it checked n fixed soon burnin money!!

Common problem on the 03-06 Avalanche instrument clusters, it's caused by failing stepper motors on the cluster's circuit board and it can be repaired. Check this page for more on how to get it fixed - Avalanche oil gauge fix

The Trainer 40 When the compressor won compress

back lighting for a couple of the climate control dash board buttons are not working. ?????? wouldn't be a fuse , bulb probably . You would need to take the component apart to replace the bulb .

Check for fuses and fusible links that may be tripped or blown.

Next, check for grounding issues someplace easy to reach like the heated seat connectors.

Most dummy lights work by choosing the warning light path over the circuit path when the circuit path is higher resistance. Which may explain your dash warning lights.

So, what I am trying to say is...you are looking for a open ground in a big big place....like under the hood at one of the major fuse/relay/fusible link points.

Check it out. Good luck and be careful.

Hello;
Are you getting the check engine light? If so the electronics may have gone out. You may not need a rebuild but you won't know till you pull the oil pan on the transmission and inspect the contents. You may also have lost the neutral safety switch. It is mounted on the drivers side of the transmission. Check those out first and let me know what codes you get.
For Ponchoboy; the clunking and hissing you hear are teminal root causes. Drop the oil pan and if it has a lot of filings and metal it is time for a rebuild.
Hope this helps; Rate me highly;
