The contact owns a 2004 Mitsubishi Endeavor. The contact stated that the front interior driver side floorboard exhibited an accumulation of two gallons of water. The contact vacuumed the excessive water but water continued to enter the vehicle. The process was repeated three times. The dealer advised that the failure was a common issue in his year, make and model and was contributed to the air conditioner. The vehicle was not repaired. The contact had concerns that the water could potentially cause a short in the wiring and lead to an electrical fire. The VIN was not available. The failure mileage was 94,000.

The contact owns a 2004 Mitsubishi Endeavor. The contact started the vehicle and the air conditioner blower failed. The dealer advised that the air conditioner connector would need to be replaced and possibly the blower and resistor. The part needed to make the repair was not available on site and would need to be ordered. The dealer made a temporary repair to the air conditioner but was concerned with the possibility of the part catching fire. The failure mileage was 77,885 and the current mileage was 77,900.updated 08/24/10. Updated 08/25/10

The contact owns a 2004 Mitsubishi Endeavor. While driving approximately 25 mph with the air conditioner activated, the front driver side floor exhibited water leakage. There was an excessive accumulation of water while driving. The water damage resulted in a rapid growth of mold and mildew on the front driver side carpet area. A water vacuum was used for the removal of the water; however, the identical failure occurred on a separate occasion. An independent mechanic an authorized dealer were notified. The vehicle has not been repaired. The contact had concerns of the safety risk involved. The failure and current mileages were 62,000.

I have a 2004 Mitsubishi Endeavor. A/C works some times in the city. Most of the time after driving on the open highway it blows warm air or not at all. The thermistor assy has been replaced as well as the resistor harness for thermistor assy. Did not correct he problem. Misubishi states (which is false) that the problem I am having was caused by the placement of a fin sensor by an independent garage. What is a fin sensor (never had this replaced) and do you have any suggestions. Thank you, bill
