2005 Chevrolet Cobalt Q&A
2005 Chevrolet Cobalt Question: door locks going crazy
Does all your door look buttens work in the car. I just had the same issue but I noticed lock/unlock button on the driver side door panel was no longer working. I poped off the door panel and disconnected the power to the door lock switch. No more popin locks. The down side is, Now the only ways I can unlock my door is with keyless entry or the passenger unlock/lock buttens. Although im sure I just replaced the door lock switch with one from a junk yard I could fix everything. - stephenwalnum
This also happened to my 05 cobalt...I am the original owner and had never experienced anything like it before...I simply took the fuse out that controlled the power locks...and that seemed to work...only thing that stinks is I can't lock my doors with my keyless entry...but it does engage the alarm still..so its all good! - ChristineC
guess what simple water on switch i threw a cup at the window trying to through it out and it splashed on the switch and a few days later it did that and i took the toggle apart and cleaned off the corrosion and bam it was salved - Visitor
MINE WAS LIKE THAT TOO,ITS BECAUSE ONE OF THE LOCK DOESN'T WORK SO I HAD CHANGE THE PART AND IT HAD STOP GOING CRAZY.. - Visitor
A sensor is going bad in your shifter assembly. When you shift the car out of Park the doors automatically lock. There is a sensor in your shifter assembly which detects when the shifter has moved out of Park and then this locks your doors. When the sensor goes bad it trips the door locks at random intervals. Most dealerships will replace the entire shifter assembly as it is difficult to replace just the sensor. I replaced my shifter assembly myself. It isn't that difficult and took about an hour. You can contact a local dealership and purchase a shifter assembly from them; Autozone and other aftermarket auto parts dealers will not have this part. - dsewardj
ok same problem 05 cobalt locks go crazy than eventualy the gas peddle no longer reacts to my foot comes and goes could this be fixed just by the locks getting fixed or is it more - Visitor
I had the problem fixed at the dealer. $80 for scan which diagnosed a switch in the arm rest which I suspect had gotten wet when I left the window cracked in the rain and $60 for labor. I've been having the problem again. If I remove the fuse the alarm goes wild when I use the key to open the doors or trunk..GM didn't give me anyway to disable the alarm.The car is too old to be worth spending for a minor convenience.I sprayed WD 40 into both switches stopped using the power lock. so far so good. - idsavant
I had this same problem. It even started doing it when the car was off. It turned out to be some door screws had damaged the wiring inside the door when the car was built. - Springman
