Hey guys umm now my heat works fine in my lady car but.. for the rear vents not blowing heat a little cold air is coming out but no heat for the rear passengers??? What could be causing this problem??
@yaser is correct. You have a stuck blend door. And being that it is the rear seats, fixing it is going to be a major pain as you'll have to take the whole center console out to get at it.
Thanks y'all... I didn't want to do it but anything for my lady.
The blend door actuator on the rear vent is not working.
An Altima doesn’t have a separate blower control for the rear climate control so there is no separate blend door in this case. Those vents are a long travel from the heater box so the temp will never be as hot as the front vents but I would look for any sort of restriction to those vents possibly causing air to back up and cool before it can get to the vents
