Problems with power windows and door speakers. Had read about issues with the wiring harness between the door and the frame. I took the rubber boot off to find 4 broken wires. I would imagine the other doors are similar. Havent ckd them as of yet. I have pictures if you like.
The contact owns a 2005 Chevrolet Equinox. The contact stated that the vehicle would drive into safe mode and slow down to 10 mph. The traction light, a green engine and an orange engine light illuminated causing the vehicle to decrease in speed. The failure continued to occur intermittently. The failure also occurred while driving through a car wash. The dealer thought that the failure was caused by water making contact with the wiring harness, but that repair did not work. The dealer stated that they would continue working on the failure, but they do not know what caused it to occur. The failure mileage was 67000 and the current mileage was 78000.
The drivers side window would not operate up or down. Sometimes the widow would go up or down on its own, without operating the switch. The wiring harness in the door was found to be defective. The wires were broken and exposed at the hinge joint. The electrical system was shorting out.
I have a 2005 chevy Equinox that has experienced multiple electrical problems. First I had ignition problems, air conditioner problems, battery being drained without cause, window control and so forth. Each time I took it to the dealer for repairs and each time a repair was made. Only after the warranty was out did I discover by accident that the problems were caused by a faulty wiring harness. The main dash wiring harness located in the left floor panel on the driver's side has signs of melting, and shorts with the slightest movement. The shortage causes the air conditioner to stop blowing and will cause the engine to completely die out. I have had the car evaluated by two mechanics who both stated, without knowing someone else had looked at it, that the car is a fire hazard and should be repaired immediately. I also spoke with a local body shop that has repaired at least one Equinox that burned due to this same wiring harness. The repairs are currently being made at a cost of $4,000. 00. I believe that this is a more wide spread problem than has been reported and hope that others with similar problems will speak out as general motors is unwilling to investigate this. I encourage new car buyers to beware of this company, as I have been sorely disappointed with their product and service. The consumer also stated there was a roaring noise coming from the rear of the vehicle. She later found out there was a problem with differential after being told there was nothing in the rear to cause a noise. Updated 12/04/08.
