Question about 2003 Chevrolet Monte Carlo

2 Answers

Electrical problem 2003 Chevy Monte Carlo Well, I have a good one for you guys that I am really hoping you have seen/heard of before. I started hearing a clicking sound coming from my fuse panels, to which we were able to pinpoint to relays. I have replaced 1 relay, which did not solve the problem, I have had it to a trustworthy/efficient mechanic (not a GM dealership)..he cannot find what is causing this demonic behavior. Here goes....... 1. The relay on the passenger side would click ONLY when you had the car in REVERSE..put it in neutral or any other gear....it stopped. (Stereo display flashed when this happened) 2. The relay (behind the enclosed box that has a wiring leading to)on the drivers side started doing it, and while this is happening it was discovered that my reverse lights and headlights were flashing @ the same pattern as the sporadic clicking... it would not stop even though the car was shut off UNTIL my daytime running lights timed out. It only used to happen IF and WHEN it was really hot out.... however, that does not seem to be a factor anymore. It will not do it ALL the time/from the same side, but it's increasing to multiple episodes daily. Only once has it happened, that both sides have acted up @ the same time. Command Start has already been removed and connections checked

    Absolutely no water... I haven't even shampooed carpets in it yet this year. HOWEVER, my car did not have a user's manual with it.... I didn't drive it for very long yesterday, but my mechanic removed the relay from my passenger side fuse panel (which I have already replaced) and the problem seemed to be non-existant. I will take it out now that it is a hot day (as this seems to be when it is the worst) and see what happens. Does anyone know what the relay controls besides my reverse lights???

    Thank you for your input - this is another suggestion I received.... what are your thoughts AND would this be an after affect from installing a command start??? (Installed 18 months ago - well over a year before any possession syptoms)

    ***For the headlights and the back up lights to be doing that, then the BCM is freaking out.
    You might try unplugging it and plugging it back in a few times to try to make sure the connectors are clean.

    Does ANYBODY know where I can download a free copy of the owner manual for this car?? The PDF on this site is nothing more than a spec sheet for Jeff Gordan's car :(

Sounds like the BCM(body control module)is faulty. Computer located under pass.side dash right side. I have replaced quite a few. It needs to be programmed once installed.

03 monte carlo wont start... turn key to AC position, hear electrical motor sound never heard before... turn to ON position, all gauges drop to zero


the noise your are hearing is the fuel pump, you might need a new battery by the sounds of it, or your ground is corroted or your connections arent tight and could be causing the power failure,check your battery system over and down to the starter, if its not grounded right it wont start it will just go blank.
