#1 of 27 cold feet for driver
Dec 12, 2007 (5:06 pm)
We love our 2007 Altima 2.5SE but now that winter has set in here in Minnesota I find that the driver position does not seem to get heat directed to the floor while the upper body is roasting. This is while control is properly set to direct heat to floor. Eventually heat works it's way down from upper levels but it takes about 30 minutes. Anyone else have similar problems or know of a fix?

We just purchased the 2008 Altima 2.5 LS and have experienced a similar occurance. We also live in Minnesota and you are right in saying that it takes awhile for the heat to take effect at ones feet. If you place your hand by the outlet, you will fel some heat coming out after only a few minutes. Problem is, it is not a real blast of air ind it does take some time to heat the feet. I think this may be due to an undersized duct in that area rather than some kind of obstruction. The rest of the system works fine for us. I take solace in having a warm butt and just wait for the feet to get warm.
#3 of 27 almost too hot
Dec 18, 2007 (7:56 am)
I live in the St. Louis metro area, and this is my first winter driving my '07 2.5 SL. I typically set the thermo to 72 or so, but sometimes the heat gets so hot, I have to turn on the AC. It's almost unbearable. Any one else having similar conditions?

When it is -25 degrees outside, "to hot" could almost be comfortable.
#5 of 27 Nissan Altima Climate control
Dec 19, 2007 (9:05 am)
I have a 2008 Nissan Altima 2.5SL which I have acquired barely a month ago. I seldom use the car air-conditioning due to the winter season, though I noticed yesterday when it was raining that when the thermostat is set to 64 deg F and up, the air coming from the aircon is hot to that point that it is causing moisture to the front and rear windshield. It is only when the thermostat is set to 63 deg F that I can feel the air coming from the aircon is cold. Does anyone else has the same issue? I wonder whether this is normal or whether I should take the car to the dealer for servicing.
#6 of 27 Nissan Altima heating stops working when car on but not moving
Jan 17, 2008 (10:10 am)
I have a 2002 Nissan Altima. The engine was faulty and was replaced last yr so its kinda new. The problem with my car A/c-Heating is that the engine heats up just fine once I start driving, but hot air takes a long time. Even after its on, it works ok, not great, as long as the car is moving. As soon as I slow down or wait at a light, it starts throwing out cooler air!
Has anyone seen a similar issue? OR know how to solve this problem.

If you have het automatic dual zone climate control, the system follows a couple presets when it's in AUTO and DUAL.
1) When heating the system seems to always use the floor setting.
2) When cooling the system defaults to bi-level (floor and chest)
3) The system will automatically tunr on the A/C if it needs to cool.
4) The system automatically adjsuts fan speed and keeps the fan on minimum until the engine is warm enough to supply warm air.
5) AUTO only automatically selects the vent setting and fan speed. If you manually select the vent setting you will also have ot manually set the fan speed. The temperature is still automatically regulated.
6) Like all new cars the A/C is automatically turned on when defrost of defrost/floor is selected. It will stay on even after another vent option is selected ot prevent fogging. You have to manually shut it off.
7) The A/C compressor is use to dehimidy or to cool. How do oyu think a dehumidified works?... it's just a air conditioning unit but the warm condensor coils are together so there no significant heating or cooling. A heat pump is just an A/C unit operated in reverse. I've always wonderd why for cold weather, luxury cars haven't been designed to use the A/C as a heat pump to provide warm air before the engine is heated up.
My wife and I love the dual zones. I always want it 3-4 degrees cooler than her, and there's those times where one of use in in the sun. We used to just shut vents, but this works much better.

My guess is that heated seats resolved that issue, at least from the manufacturer's viewpoint. Plus, the reversing valve to put the compressor in heatpump mode would probably cost $1.98, and they couldn' t recoup the cost as easily as selling heated seats at a higher option price...still, a great idea, though.......

Another would be to add about 500 Watt of electric heating elements (similar to a small hair dryer), before the evaporator but you would need to upsize the Alternator by at least 300 Watts to compensate for it. On the opposite side, the increased load would make the engine warm-up faster.
If you want your car to heat up quicker in the winter, turn on the headlights (150Watts in inluding marker and tail lights) and rear defroster (~200Watts), stereo (50 Watts). That's about an extra 1/2 HP. Not a lot, but every little bit helps. If you don't believe it, watch the RPM's change when you turn on the rear defroster and the alternator is loaded.
#10 of 27 Problem with vent sysytem
Mar 28, 2008 (7:05 pm)
I recently purchased a 2008 Nissan Altima and Im having problems with the heating and cooling vent system.While using the heating/cooling or defrost, at any speed adjustment on the fan,I lose air flow through the vents.I can have the fan on the maximum speed and still there's no air flow from any of the 3 vent ports(defrost,front vent and floor vents).I have taken my vehicle back to the dealership service department 3 times since my purchase and have been repeatedly told that there's nothing wrong with the vehicle.Has anyone experienced this problem with any of the newer model Nissan Altimas?If so,what was done to correct the problem.Any help would be greatly appreciated.
