Hi,
The otside handle of the Door behind the driver seat has gone bad. It gets stuck when I pull it, it remains stuck in that position. I need to press it hard in so that I can open the door next time. It does not go in by pressing hard .. I need to hammer it with my wrist ...
How can I fix it ? Can I open the door panel from inside somehow to see what is wrong ? I am afraid to open it as it has Air bag .. will it harm the air bag if I try to open myself ? What are the precautions that I need to take. Anyone please help ...

 

No one opens door

 

I wonder if people enter through windows [:'(]



Does any one know how can I open the door panel on the door from inside, which has leather cover on it.
I mean the part of door inside of car which has leather , handle, windows open/close control... how can I open that thing.

I am afraid to pull and play with that part coz it has airbag .. I dont want to screw it up .. Does anyone one has experience of opening it ? I am sure it can open and I can see the glass of window opened in the door somehow ...

Any ideas ?
