Hi i have a chrysler town and country 2008 and for some reason my sliding door wont open while engine is on
But when engine is off it opens

 

It won't open while in Drive. You need to be in Park to open any of the power doors.

 

Yeah im at park but for some reason it still wont open

 

Don't know if this would do it, but i'm sure the doors used to have an auto lock function, that could be turned on or off via the overhead info panel.
I'd think a locked door should open, but worth a check.

 

I dont see a on and off switch for auto lock but dont know if my t&c is equipped with it

 

It's in the software for all Chrysler Dodge American [country codes] or euro, even for driver/both/ front doors but you can't get at it without a pro dagnostic meter.

 

No need to start a new thread on the same subject, it'll just get confusing.
On my 2007 model, the auto lock function is controlled in the overhead computer settings.
What about the child door locks, have you checked them?

 

Yeah already have

 

That, [lock/unlock] correct me if I'm wrong in the EVIC is to stop anyone/child intentionally/inadvertently opening a door. It is auto executed by the BCM above 15 mph. It exists on many platforms but is pretty much across the whole Chrysler/Dodge range software(s).

 

Correct Q, to some extent. It prevents the doors from being opened from the outside, with or without the engine running.
