Affects Hummer H3, H3T · 2006–2010 — about 5K vehicles.
The hazard
On certain vehicles, the connector module that controls the blower motor speed in the heat/vent/air conditioning (HVAC) system could overheat under extended periods at high or medium-high blower speed. If this were to occur, it could result in the plastic around the connector module melting by the heat generated, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will replace the female connector and harness.
