Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Can you tell me what liter engine is in your model here and we can continue from there?
Let me know so we can continue,thanks Pete.
Let me check into this really quick.I have an idea of the fault but want to make sure.I will post back here shortly.
First off.Does this affect the radio dash lights and all other components that usually light up with the dash lights?
O.k.,but does this affect all back lighting like the back lighting for the radio and heater controls?
O.k.,this does sound like it is working backwards or incorrectly here.This leads me to believe the common ground that these lights use is o.k. since it does work but that the fault is in the BCM (body control module ecu).This sends the voltage signal out to these lights to operate them properly.It sounds like there is an internal electrical fault in the BCM causing this issue here.I have seen several BCM failures in the past before for issues similar to this with the BCM needing replaced.
It will need replaced with a new one as a used one is already programmed to another vehicle and cannot be reprogrammed for your model.Once installed it will need programmed by a GM repair facility that has access to programming like a dealer.The cost can run around $300 to $600 to have replaced and programmed all depending on the shop/dealer costs for the part and labor charges.
I would have the BCM fault codes checked with a compatible scan tool that can plug in and communicate with the BCM to see what codes are set.Once this is done any codes set will help diagnose to help locate and correct this issue here.
