2009 Trailblazer doors hitting each other

[Junior1s]

Hello TrailVoy community,

I have been a long time member. I am the original owner of a 2009 Trailblazer red jewel tint coat LT3 black leather interior. I have 181,000 miles on it and it runs flawlessly!

The driver's door and left rear passenger door hit each other as they close. I always have to open the driver's door first before I can either open or close the left rear passenger door otherwise they will touch (rear of driver's door hits the front edge of passenger door).

I have owned the truck since new and never had an accident.

Any ideas how this happened?
How can I fix this?

Thanks!

Mark
