Are front blazer door interchangeable between 2 doors and 4 doors. Also, can you use older model door? For ex: 98, 99?
i have a 2004 blazer 2 door. I need to replace the driver side door. But its very hard to find blazer parts. Any info or advice would be much appreciated. Thank you.

 

Hopefully you pop back in to check this but 1995-2005 Blazer, S-10, Sonoma, Jimmy, Bravada, and (probably) Hombre doors are interchangeable. Shouldn't run you more than $75 at a you-pull-the-part style wrecking yard.

I put a 2003 driver's front door on my 2000 blazer. Just pull the handle/lock off your old door unless you want to re-key. It's also a good time to check your hinges for any warping around the pin holes/toss new hinge pins in.

All you need is standard tools, (hammer and punch for pins) something like a cargo strap/buddy to help hold the door, and patience pulling the plastic connectors off of your (probably brittle) inner door skins. If you get one with manual windows and want to swap in your electronic ones you're looking at a more in depth project...

Bonus: get a $2 spring compressor for the door spring unless you like to live dangerously.

 

Doors themselves are the same, wires and harness change between the years, but arent hard to swap over
