I'm a new '06 owner & a complete disaster when it comes to finding answers via search features. So please bare with me...

Since there are no longer "Hummer' dealers, where do I go for parts?

Currently I need a door for the storage compartment in the back passenger side and the latches also.

My outside rear view mirrors vibrate incessantly, although tightly fastened to the body. Is there a fix for that?

Any help & direction is most appreciated...

 

For most Hummer specific parts, the best place is online GM parts pages.
Some of them are:
GMPartshouse.com
GMPartsDirect.com
GmPartsonline.com
and there are many more.

Here's your compartment door - INTERIOR TRIM - QUARTER PANELS for 2006 Hummer H3

For mechanical/electrical parts, places like Rockauto.com are great.

Any GM dealer can also get Hummer parts but that is the MOST expensive route to take for ANYTHING.

 

Yup, just remember that your Hummer is a GM (Chevy).

 

car-part gets you all usa junk yards where they buy and part out cars. lots of hummer parts, computer linked everywhere.

 

or get to know your local dealer, mine is great, all Hummer parts at 10% over cost. even if they have to order it. Plus I dont have to pay shipping and they are there if I need them. Maybe because I have bought 2 cars from them, a 2015 Corvette and a Sonic for my kid, but they treat me right. Plus I support the local economy.
