2008 Hummer H3 alpha with factory tow package trailer routed between sharp body panel and bumper causing vehicle motion to rub the wires. The exposed wires short to the body and cause high current melting interior wiring. This problem has been imntermittent for about 1 year and have had GM dealer troubleshoot the failure of trailer brakes and lights with no solution. I discovered problem by removing rear bumper. Problem can be avoided by shielding wiring and smoothing the sharp metal edges it crosses.

As many have explained before, my blower motor all of a sudden went out I started to read online what it might be and found that everyone complained of resistor harness wire burning out or the plastic melting. And just as everyone said I pulled out the harness and it was burn completely out. GM this really needs to be addressed, how many people need complain, or something possibly happen to someone before your company takes action, with all the recalls going on with your company you would think you guys would learn.

I was driving along and there was smoke coming from below passenger side under the glove box. Pull over and saw it was a resistor with two screws. It was burnt, I unplugged and drove home. Then searched internet and there are hundreds of people with the same problem. This needs to be a recall asap, before someone dies in a fire.

I have the same issue as hundreds of others with GM's faulty blower motor resistor. The blower motor resistor and wiring harness have failed 2 times now. Melting to each other. Luckily no fire, yet. These are expensive vehicles, and GM should own up to the design flaw and issue a recall, and or offer a repair kit that truly fixes the flaw that owners can install as the location is fairly easy to get to and work on it. The purchasers of these vehicles should not have to put up with this quality flaw, and risk themselves, family and friends. GM - do the right thing and avoid major lawsuits.

Radiator end tank ruptured releasing coolant on everything under the hood and getting on the windshield. Research of this finds that there is a defect in the design of the factory radiator which GM refuses to take action on. Had this happened at higher speeds, this could have been a much worse situation.

I looked on the internet to find out why my heater blower was not working and there were lots of complaints about the wiring harness and resistor burning out. I checked mine and sure enough mine was burnt on the wiring harness all the way through the plastic. GM needs to figure out why it would cause it to malfunction like that cause it could cause a fire.

Smell of burning plastic and the A/C stopped blowing. The A/C works on the lower speeds. Burnt/melted plug on the A/C resistor plug. From what I have found online this is a very common problem with H3's at about 40-60K miles. Why wont GM do a recall if this is a daily problem with H3 owners. How many H3's have caught fire from this " it was over a 110 degrees when mine went out. What if I had young child or an elderly person in the vehicle at that temp "
