Even when I hit the a/c switch to off, turn the dial away from defroster, and turn the blowers to 0 (off) the compressor continues to run indefinitely as long as the car is on. To turn it off, I have to stop and turn off the car. It's not only fuel inefficient, but sometimes I have to turn the heat up to keep it from getting too cool, if I've wanted only to turn the a/c on to cool down the car. The dealership tells me that for two years (04-06) Nissan did this with their Sentras and it's normal. Is it?

Do you want the service bulliten number? It is true Nissan a/c compressor continues to run to de-humidify the air after defrost is used. The inverse when cooling the inside air A/C the compressor sometimes can be turned off. Actually the compressor during cold out side temps lower head pressures only takes 2 hp VS 4 hp summer load. If The Compressor does not oil and r134 circulated the compressor seal may start to leak so next summer you will say that darn nissan needs freon every year. Not only Sentra' Altimas Xterria defrost on to run the compressor Only cars with manual a/c controls. If it bothers you you can install a toggle switch under the hood on the single A/C compressor wire and turn the power to the compressor off. # NTB03-048A Bulliten it is not much a problem your car gets 30 MPG if driven easy so cool down.

It doesn't sound normal to me, but I will tell you that there are a number of cars that have automatic climate control. It might do you well to look at the owner's manual. If it proves out that there is no switch why not just go and have a switch installed or do it yourself.
Note to, transtime, I am afraid that Not only I and a number of other people don't know why you don't want to buy American. For the most part the Manufactures from Japan have the most American built cars. I just bought another Toyota, it is 85% American parts, my last new Ford was 71%, I would also point out that all of these companies are sold on Wall street so ownership isn't one country or another.

Your car is designed for the compressor to run in defrost. They have been doing that for years and yes even on Fords and GM products. This is to keep the oil circulating in the system so that it does not burn up your compressor in the summer time with a "dry" start. The compressor will go off in the other modes such as in the panel or panel floor. Hope this helps. good luck

1; In the fuse/relay box under the dash pull the fuse for the a/c and see if you can disconnect the wires just before the compressor. If compressor still runs after that the compressor clutch and pulley a frozen together, Replace Compressor.

You deserve it for buying a Japanese car instead of an American one!
