Intermitant problems are the worst! When this problem happens, opening door via power, door appears to unlatch, opens about an inch then stops moving but the motor is still trying to open it. It will torque out after 3-5 seconds. Can manually open the rest of the way but is stiff. When opening manually from the power-open-stopped position, I will hear a sound as soon as I start to move it; like insulation material under pressure being released. Make sense?. Once open, power operation performs normally. I've had my Chrysler dealer work on it. They managed to make the problem happen a few times with the diagnostics computer attached. No codes appeared on it. I've listened to the unlatch/move sounds and to me no obvious change in sounds from normal operation to no-open problem other than the motor torque out when hanging up. Any suggestions?
