Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HI there, I am Cam. Can I get your first name please? Did you happen to get the code number that was set for the transfer case system?
OK Pete, the codes would be scanned with a scanner, and its the diagnostic trouble code. Where, that is done at the port under the dash. Without the code I can only guess at what the issue is. You said you changed the buttons, replaced the module, so the likely suspect aside for wiring is the sensor in the shift motor under the vehicle on the transfer case. The sensor is not bad to change out with the directions attached, but i would like you to get the truck scanned and confirm code C0327 first before spending the money on the sensor.
No Pete, if the fluid is simply low it will not set a code. If the fluid is low and it has caused the clutch pack to burn up, that will cause a code. So was the shifting module you talk about on the side of the transfer case? IF so then it still could be the sensor, could be wiring, connections, the buttons, the front axle actuator, grounds, we really need the code number to narrow down the issue so you don't waste more money trying to replace parts that are not needed.
I understand. Well some parts stores can scan for free. Or you can get a simple code reader like a Bluedriver that is about 1004 and will read ALL system codes from 1995 up to current models using your smart phone.
Sorry, blue driver is the device that reads the codes and 1004 should be 100$ from Amazon so you can read the codes yourself. I know this is a pain, computerized systems set the codes and we need those to be able to diagnose and fix the issue.
That is correct Pete. With that code I can get you all the information, but until then, we are spinning our wheels.
I do help with directions, parts to replace. Pete I am a GM technician working part time on Just Answer to help customer such as yourself fix your vehicle, but there are limitations such as what we have here. There are some issues that need no codes, but yours I am sorry to say does need the codes.
