Door wont open
Today I got in the car and realize I forgot my wallet inside low and behold the door wouldn't open and the window didn't index I had to use the floor latch to get out. Got back in and the same thing, I had to make a run and about two miles down the road the window went up and when I stop the door open and the window index when I close the door. After it sit for a while it did the same thing all over again. It open from the outside with no problem the window goes down but not all the way up with the button. The passenger side works fine, 2007, any thoughts.

Does it work when the car is running, if it does (correction)check the battery volts
Check the indexing with the window switch, when the car is running, up 3 seconds, down 3 seconds....might be in your book
Check the switch on that side
Could be the door latch is going
You can probably search the forum on those items, plus just the window operation. If not Google them and something will probably come up on your year and/or C6 window operation.
If it's a window motor you might find out that too.
Hope that helps, someone here has probably gone through this and could give you more things to check, Good luck.

You have some symptoms of a battery on its last legs. Sometimes things work and sometimes they don't. The fact that the window went up when you started driving is the clue that you have power issues. Opening from the outside is easier if the car has been idle for more than 30 minutes because the computers are mostly powered down. Open the door and the load on the battery goes way up and then the door won't open again because the door computer is getting flaky. Each door has its own computer and one could work while the other won't under these conditions.

I also think it's weak battery, from past experience when the car starting acting weird it was time for new battery.

I had a chance to have the battery load tested today at two different places and the result was:
voltage - 12.76
measured- 734 CCA
rated -650 CCA
Temp - 83
Its 7 mos old, so on to the next could be.

Mine does the same thing at times. Usually when it's right when I get in the car and running. Then when I tried to get out and I had to hit the manual pull. It did it the other day and I got it to work by shutting the engine off and putting it in reverse and bang it opened just fine. I really hate that they have gone to electric door switches (openers) as it could malfunction and in the panic of getting out very fast in an emergency result in being trapped in that nano second.

Bassman50, I never thought of that about the cell phone. I carry it in the center console in the cup holder. I'll try going out there and try it several times with out the phone. That, or put in in the rear compartment and see if that helps. At first I thought it was the switch as it was warn a bit like they get so I replaced the switch and with the same result.

Also 90% of switch problems is the exterior switch. Interior switches fail rarely.

The outside switch has never failed to work getting into the car.
Only the inside door switch (button) fails getting out and only at times.
I love my C-6 but they certainly have there strange electrical gremlin's

If you have a manual shift, I think you have to be in a gear (reverse?) with the brake on to open doors after you turn the engine off. Check you manual. If the door works from the outside, the fob, door pad, and latch is probably working. Check your manual(book).
You are dealing with the Fob(outside switch), the door latch mechanism(where the door locks against the car), and the door pad that you push to open the door. If all of those are working(door opens from outside) then it would be the inside switch(intermittent) or some other electrical/computer problem. Maybe the position of a manual shifter and brake and after turning the engine off before it goes to sleep mode.

Change out the outside pad switch.......I did the DIY clean to my exterior door pad, worked great but very very sensitive, I barely had to touch the pad and door would open.....then I started having the problems you describe, door would not open from inside and window indexing issues.... bought a new door button switch but still same issue, then I bought new pad exterior switches from Cultrag Performance and no issues since.........

I took the pad off and cleaned it and it still didn't work so I switched it with the passenger side pad and bamm, so I order two new pads might as well change both. Thanks.
