I encountered a strange phenomenon with my 2016 Jeep Patriot earlier this evening. Vehicle has about 36,700 miles on the odometer. It has manual control heater and air conditioning / HVAC system. I was installing a seat cover on the driver side seat when I started to hear a climate control motor actuator power up. To me it sounded like the recirculation actuator either opening or closing. Ten to 15 minutes the same actuator powered up. And 10 - 20 minutes later the same actuator powered up. I was working on the seat cover for about 1 hour total time and the actuator powered up 3 times. The key was NOT in the ignition. The left front and left rear doors were open. The interior dome lamp and other lamps were switched OFF with the control on the turn signal stalk. I was moving the driver seat forward and backward while installing the seat cover. I wonder if moving the seat was generating some vibration that somehow affected the actuator position feedback circuit between the actuator and the HVAC electronic controls? You would think that with the ignition in the OFF position and key removed, the actuators should not suddenly power up. So there is some phantom operation occurring with the HVAC electronic controls. The HVAC controls are probably engineered for similar operation in all late model Chrysler vehicles. Has anyone encountered this rather strange behavior? Any TSB about HVAC control behavior? The only concern this causes me is that if this goes on continually and the vehicle sits for an extended period of time, the battery could be depleted prematurely. I will have to see if I can recreate the situation.
