C6 passenger door opens ONLY after 10 second delay
I have an '09 C6 Base Vert that I have owned for 9 years with no problems. About a month ago I went to take it out and had forgot to leave the battery tender on and the battery was dead. I charged the battery, re-indexed the windows, reset the seat and all seemed well until I tried to open the passenger twice within 10 seconds. The door operates correctly (window index and all) unless it closes and you try and open it again immediately. If you wait 10 seconds ( not 5, 6 .7 .8. or 9 ) the door will open from the outside or inside O.K. (driver side works immediately). I have looked at the signals with a Snapon scanner from the door switches and all looks good.
WHAT THE HECK IS GOING ON????????????? Does anyone have any ideas???????
Disconnect both battery cables from the battery,
Now touch the battery cables to themselves a few times (away from the battery terminals), to drain down all the charge of the modules in the car .
Note, if you only want to remove just one cable from the battery, then will need to leave it disconnected for about 15 mins, to allow the module charges to slow drain down instead.
Now connect the positive battery cable first, then the ground cable last.
This will reset all the modules in the car, to fresh state without losing any of their programmings.
Simply, when the battery did drain down under 12 volts, it low volt glitched the modules, and since you did not allow the modules to full drain down to factory reset them before the battery was reconnected in a 12V+ charged state, some modules are still in a glitch state.
And on a side note, when you did try to start the car with the battery drained down, will have a lot of DTC history codes that where caused by the modules not having 12V (when they did glitch). So tech II or some other scanner that can get you to the body/EBCM level and history, and clear the codes caused by this event.
I tried the "complete battery drain" and that did solve. not the problem. I believe that it is the latch mechanism. It hasn't failed completely and a 10 second rest allows it to work. I am going to replace the latch assembly..

If you experience this problem trying to open the door from both inside and out I would agree the latch mechanism is probably the culprit. If just from outside it is probably the pad. You can search on how to clean it or simply get a new one.

If motor is firing, then would just use some lithium spray grease to relube it in place, or just pull it apart to re-grease the binding parts.
A follow-up to my post. I finally replaced the latch mechanism. I saw that to open the latch mechanism you had to grind off the two rivet posts and then re-drill through them to close it backup. Too much of a hack. I didn't want to replace with a used unit and not know how long it was going to last. Accessing it in a vert wasn't to difficult removing the door jam covers, but in the process I popped one of the retainers off (plastic ) and needed to re-glue it. I do some outside work for a body shop and they turned me on to a plastic epoxy that is fantastic. I also found a Chevy Dealership with good prices. Beat my local dealer by over $100
