I have not taken it in to get looked at as I do not have the $$ for a diagnostic fee. It may be something very simple or it could be something very complicated. I'd like some suggestions on where to look, really. I just can't afford to take it to the dealership to spend $100 or something to have them tell me what's wrong and how much more it will cost to fix that. It's been going on for around a month
This is what I've gathered so far. The signal makes noise, the door makes noise and the speaker makes noise. Now when the signal and the door do not make noise the speaker is also silent which leads me to believe that all of the noise could possible come from the driver side speaker. There may just be a loose wire on the speaker inside the dash. I will check there for now and I look forward to any other suggestions.

Hi there, believe it or not I own a 2008 Colbalt LT and the exact same thing is happening to my car. I have looked at all the fuses and even looked for any exposed wire that may be hitting against something and making it short out. I am baffled also and any other suggestions would be greatly appreciated. This issue just started 1 week ago. It is driving me crazy especially when trying to listen to the radio.

I ended up fixing the issue! I replaced the speaker and all is well. It looked like when washing my car I had gotten some water inside the door from the pressure washer at the DIY car wash. It's hard to spray all the soap out of the window seal and get it clean!
Anyway, replaced the speaker with one I got from the dealership and all is well. 1st I suggest swapping the speaker with the one on the passenger side to make sure the speaker itself is actually the issue. I swapped them and the speaker was definitely dead. Hope this helps you out.

I am soooooo glad to hear your reply. I have thought the worse about the wiring and electrical system. In my area the weather has been very bad and it has rained quite a bit. Possible that this rain has somehow effected that speaker also. I will do what you suggest and will let you know if it works for me also. I do thank you again and I am thankful I found your post with the same issue. Again, Thank You and I will post back to let you know.

Have you had the chance to take your vehicle to the dealership to be diagnosed?

I would encourage you to have the vehicle diagnosed by your local GM dealership. Please keep us posted on any information from the diagnosis.

Ya Im having the exact same issue with my 07 cobalt ls. I havent taken it in mainly because I dont think I should have to on a newer vehicle. I tried changing speakers, but no hope yet. It seems like GM got a little sloppy with this portion of the the assembly for the cobalt lines. If anyone knows which wires are the ones that went bad, then please let me know. Thanks!

I believe it will be the driver side speaker. Dampness may have gotten in the speaker or the cone on the speaker has gone bad. I replaced the speaker and have not had any issue since. If you have any other issue just let me know. I have had some great help with this site and had all issues fixed to date.
#36 of 37 Water leaking in
Jun 16, 2013 (3:48 pm)
My Cobalt has sprung a leak!!! I have a 2-door and recently have noticed when it rains the back seat floor board on the driver's side gets soaked. We have torn the car apart three times trying to figure out where the water is coming in at. Checked the sunroof drains and they are fine. The trunk is completely dry. Tore out the back seat and there is no water pooling under it either. The only spot where there is water is in the rubber seal on the bottom of the door frame towards the rear part of the door. It looks like water is draining down through the door onto the rubber seal and then makes a trail down the plastic trim and onto the carpet. When it rains, only a small part of the seal is wet right at the spot where it trails down to the floor. The rest of the rubber seal around the door is completely dry. I am thoroughly confused as to where the source of this leak is. We have attempted to spray the car to simulate rain but see nothing. Today we removed the door panel. We poured water around the door to check for leaks in the door and around the seals but see nothing there either. Very frustrating.

Since you've isolated the source to be the door panel and it sounds like the seeps in the H-body cars, I'll suggest what they have.
The door panel has a heavy plastic sheet between it and the metal door. That sheet is glued to the metal with a heavy black mastic. IT ages and doesn't seal well in spots or it has been pulled away for service and then put back when it has aged and lost its tackiness.
The glue lines are shaped at the bottom so that water on the metal side is directed into 3 holes that let it drain back through the metal and then out the drain holes in the bottom of the door. Usually the water is seeping past the mastic at the V-point.
The solution is fresh black goopy sticky stuff from a supply place for auto shops and a new line of mastic on the plastic.
Here's a link to a write up with pictures about the H-body door setup. Good luck finding your source.
