Whirring / clicking noise from fuse box - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Jterb69 · 06-22-2014, 06:43 AM

I have just over 1,500 miles on my 2012 ZL1, and have had no problems over the last 2 years. The other day I jumped in her for the first time in about 3 weeks. When I unlocked her I heard a continuous whirring noise coming from under the hood. The car started fine, but about 8 miles into my trip, she started bucking and the check engine light came on. I pulled over to assess the situation and she stalled. Was able to get her restarted, but she would not stay running without constantly fluttering the throttle. I turned around and limped her home. Yesterday took her out again to top off with new fuel and fought her the whole time. I noticed when I got home there was a clicking noise coming from the fuse box. All the noises from the fuse box appear to be coming from the K26 relay (PWR/TRN). You can feel it vibrating when you touch it. I have an appointment with the dealer on Friday, by am a little worried about driving the car there for fear of doing more damage. Anyone have any similar experiences? Thanks

What codes are being thrown? I would assume you got a CEL.

Try seating all the fuses you will find many not all the way in. Also some on the forum have reported the rear connections not being tight but I have yet to meet anyone with that problem so cant ensure its validity.

Could it be a bad relay?

Yes, I have learned that relays can work part time, unlike a fuse. Learned the hard way at my job, I am a power plant operator. Anyhow, check the relays, but I would not hesitate to driver it to the dealer as it is under warranty. I please stop caller the car her, that might be part of the problem...lol...

I am not sure what codes are being thrown, I will have to find out from the dealer. I did move some of the like relays around, to see if it was that K26 relay, but had the same result. I try checking all of the fuses and relays to see if they are seated properly.

Jterb69,

Heard from the dealer today. They need to replace the engine control module. Part is on order. Hopefully, this will solve the issue.

Picked up the car on Monday and everything seems to be back to normal. No noises from the fuse box, and the car runs like it did the day I picked it up. Dealer stated this was the first ECM they have had to replace in a Camaro. I am not sure if any other ZL1 owners have had a problem with the ECM or not. Hopefully, the issue does not come back in another 2 years.

Thought it might be a good idea to list out the codes the dealer found when assessing the condition. They are: P023A, P025A, P0300, P0036, P0050, P0053, P0054, P0056, P0059, P0060, P069E, P0443, P0480, P0481, P0645, P0685, P0690 & P1682. There was voltage error on Circuit 2, this circuit monitors the engine run relay and this relay supplies the current to most of the sensor for normal engine operation.
