Asked by Sep 09, 2015 at 10:23 PM about the 2010 Nissan Titan LE Crew Cab 4WD

Question type: Maintenance & Repair

I have a 2010 Nissan Titan.  The A/C will sometimes blow out warm air on the
drivers side but cold air on the passenger side.  The system is on automatic
with the temp setting the same on both sides (68).  Any ideas on   the cause?

If the air is cool in pass. side and warm on driver's side, you might just be low on refrigerant. But if it's cold on pass. side and hot on drivers side, you probably have an blend door actuator problem of temp sensor problem.

I recently got this problem on my Armada 2008. stephend103, your answer is ambiguous, can you try again please?

If you are running the a/c when it is hot outside, and there is a small difference between the temperature of the air on the driver side versus the passenger side, it could be due to low refrigerant. But since it is winter, and I assume you are running the heat, your problem is going to lie in the air distribution section of the HVAC system (i.e. behind the dash). Most likely a temperature blend door actuator is not working. This could be caused by a bad actuator, or a bad inside temperature sensor, or even a bad HVAC control head.
