I enjoy working on my own vehicles. I always have been able to purchase either a Haynes or Chilton manual for my rides. Is there anything for the H3 or H3T vehicles that is available? I am always needing schematics, special tricks etc...for install of extra specialty parts, that the dealers seem "offended" of.

 

u can download for 15-25 bucks, type in "hummer 3 service manual" any search engine.
maybe a bootleg copy/copy for less

 

Awesome thanks! I have tried to search in the past with no luck. I will give it a new try...

 

Or try this:

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

I bought one from this seller and received a CD with the entire workshop manual in PDF. Really useful, very detailed. And it's less than 20 bucks including postage. You can share it with other H3 owners in future.
