Like many others on the forum, my XD developed a problem with the A/C. After 3 years and 53,000 miles, the A/C would blow cold on the passenger side and warm air on the driver's side. This problem actually started a few months ago but I could get it working correctly by turning the temp knob all the way to max heat (90) and back down which would get the cold air coming out the driver's side. That was until a few days ago when the trick would no longer work. Taking the advice of others here on the forum, I ordered a new Air Mix Actuator assembly P/N 27732-EZ03B from Nissan Parts Deal. Total cost with shipping was less than $65.00. It took all of 3 or 4 minutes to swap out the old actuator with the new. The air works like new which is pretty important here in Arizona's 114 degree summer. Ahhhhhhhhhhhh.
