Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello and welcome!My name isCustomerand I can assist you with your question.
Do you know what is making this screeching noise? Can you take a video and upload it and send it to me so I can hear it?
Could it be from one of the relays?
Does this only happen when you turn the key to the CRANK position or does this happen when you turn the key to the "RUN" position?
It could be a relay due to a bad connection or low voltage. Have you checked the battery?
Ok, keep in mind, without me hearing this noise and without knowing the current battery voltage it is hard for me to say for sure. I am just giving you some ideas to try and help.
Ok, then the battery should be ok. I suspect it might be a bad connection at the fuse block or a bad fuse block. But again, it is hard to say without looking or doing any testing. Let me know.
