SOURCE: DOORS displays on DIC in 2007 Hummer H3. All

i beleive those have their own door switches in latch i would try to clean latches with spray brake kleen then blow out, lube with a spray lube like wd40 that may solve your issue. while your doing this remove negative battery cable so the ecm has to recheck doors system.

What is the run wire to the radio in a 2006 h3 hummer?

There isn't one. You have two choices. 1st and best is to purchase the correct interface harness that includes a module that provides the switched power lead or 2) run a wire to a fuse in the fuse box that turns on with the ignition. All GM products since about 1999 have a class 2 data bus system. The data bus wakes up the radio when the ignition is on. The correct harness retains this feature as well as all of the warning chimes (door ooe, key in ignituon, etc) and allows the retention of on star as well. Harness is available from most online sites, best buy, walmart, most auto part stores, local audio shops...etc.

Why do I lose radio signal on my 2006 h3 hummer when I turn on my ignition? My radio works fine until I turn on my ignition.

If it works at the accessory position and not on the run position. I would go after the run wire to the radio. If other things don't work in the run position, look to the ignition switch.

Why will my 2008 hummer H3 door locks with key but will not unlock with key. the key will not turn to unlock

The lock assembly in the door is faulty. It gets tricky since Hummers are no longer in production. Changing the door lock cylinders will get you a different key than the ignition. Any GM dealer should be able to get you the parts.
