I check today if the Driver door aligned with the rear door I see that the driver door goes little more inside then the rear door.

Can this result a problem?

 

If the drivers door is closer to the body, and you still have a gap on the seal, I would replace the seal. If the back door sticks out a little from the body, but there is no gap in the seal, it sound like the drivers seal got "warpped" somehow and is now failing

 

Ok, thank you DonL I will search online if I can found one because the GM dealer in my country stopped bring any parts for BLAZER/JIMMY.

Do you know online sites in CANADA sale gm parts or the door seal in affordable price because I have address in Ontario?

 

I can take a look.

 

Everything im finding gets shipped in from the states, unless bought at a local store, prices are about the same. Not too expensive.

 

Ok, thank you DonL
