Double check your ground connections and the charging system voltage. These had problems with the alternators getting wet and causing issue. Also GM products had issues with the side post batteries. Clean and snug is key.

    I just had a similar situation but scarier. My H2 door locks unlocked and locked and then I lost power to the engine while driving 65 MPH on feeway. I had no steering power and no brake power. luckily I could pull over. I started the engine like nothing had happened. It was really scary. One posting I saw somewhere else indicated the following which may be of some value.....It turned out to be that the alarm was faulty

This could be your micro switch in the door lock itself , by a vw golf type four and other modelss you have an automatic locking function if you unlock your door but don't open it and most of the time it's the passengers door as it is used the least.firstly check the wiring to the lock and between the door and the body then checck the micro switch on the lock if its correctly seated and if its make a click when you press on the metal arm .

Check door switch connection and operation.
If the door switch is part of the door lock mechanism, within the door itself, then remove door panel, disconnect the mechanism's electrical connector and re-check that the interior light no longer comes on with that door ajar. If it doesn't, then you likely have a faulty door lock mechanism, which you will have to replace.
This faulty switch will also have the affect on your random central locking function.


This is not likely connected to the engine performance issue.

CHevy cobalt door locks- lock and unlock while I am driving had key fob reprogrammed and it was ok for about two hours and started all over again. What can the problem be?


Could be a problem in the shiftier. Your car doors lock automatically when you put the car in drive. They unlock when you put the car in park. The switch located in the shiftier can go bad causing the locks to randomly lock and unlock. Also, this can cause the key to get stuck in the ignition.

Hazard lights flash by themselves, doors won't stay locked (unlock by themselves) key fob won't work.


I has a similar problem and I just took the battery out of my remote. I think there is a problem/ short in the remote. It's as if the button is being pressed when it is not. I will use my spare one in the mean time. It was driving me crazy becuase I was driving long distance at the time and when I removed the battery it stopped. I hope this works for you!
