This may have been beat to death but I could not find much on this topic. My '08 JK right hand drive heater motor quit and I attempted to find a replacement with no luck although I did not try the stealership. I purchased one from NAPA but it ran well with no air output. I reversed polarity of the power wires and then had good air output but it screamed so loud I could not stand to use it. I then purchased a motor assembly from GWA Auto Parts on Amazon. It also did not put out much air but when I reversed the motor connections it ran quietly and put out a good blast of air. I felt some other RHD owners may find this helpful.
