A/c heater motor resistor overheated causing smoke throughout the passenger compartment on the highway this is the third replacement of this part, the wiring overheats and melts the connectors this is a very common problem on hummers of all types. My sister owns an h3 as well and has had to replace this twice on her 2007 model h3 due to overheating an melting the connector. Is general motors going to wait until there are numerous fatalities or vehicle fires to rectify this ? A fire in the passenger compartment while at highway speeds is dangerous to say the least
Overheated and melted resistor and wiring harness for the HVAC blower motor on a 2006 hummer h3. This has happened to my vehicle and a friend of mine. Also many owners on the internet have had this same problem. It is so prevalent that many parts suppliers are advertising the parts for sale.
