    My nissan 2000 xterra also has warm ac air blowing after ac freon was replaced for $150, then I noticed the fan behind the radiator does not come on, and then the fan clutch disengages, and warm air blows. This problem blows, can anyone find the relay or fuse that controls this??

    thanks kindly

One suggestion. Have you checked the fuses ?

I would check the AC or blower fuse to start with. If you have the drivers manual it will show you where the fuse box is. Typically there are at least two boxes to check. One in the Engine compartment and one in the passenger cabin.

Look inside the lid of the fuse box to see which fuse may apply to the AC circuits or the blower and check to see if they are blow. the metal link between the two posts that plug in. If the link is missing you need to replace the fuse with one of the same rating. Make sure you know where you took the fuse out from and put it back in the same slot if its good. Check all the main fuses if possible to see if any have blown and replace if they have.

I seem to always have problems with the air conditioner in my car. I need to get it repaired soon. I have tried to fix it myself the last few times, but so far it hasn't worked. I may just have someone else do it. I think my dad would know more than me.

If your car air conditioning vents blows out warm air when your car engine is hot or under a lot of stress, this means that your car is equipped with a safety feature that shut off your air conditioning compressor when your car engine is hot or under a lot of stress thus no problem in your car air conditioning system.

However if your car air conditioning vents blows out warm air even if your car engine is not under a lot of stress or within the operating temperature then that’s a different story and this means a problem.

More often this kind of problem can be traced depending on the behavior of your car air conditioning system. If your car air conditioning vents initially blows out cold air then after quite a while it starts to blow out warm air then the problem can be traced to a freezing up expansion valve.

If your air conditioning expansion valve freezes up the flow of refrigerant to the air conditioning lines will be block temporarily thus causing your car air conditioning vents to blow out cold air initially then afterward begins to blow out warm air.
Your car air conditioning sometime blows warm air

Sentra AC

There's a 10amp fuse that powers the ac clutch relay and compressor. There are 15amp fuses that power the blower motor and the ac control switch. All of those fuses get power from the key switch. The resistor and fan switch provide the ground circuit for the blower motor.
I would want to know if those fuses are getting power, and if the control panel is working. You should be able to ground the blower motor and make it run on high, and that should not have any effect on if the ac compressor is running or not.
It could be a key switch problem in that the circuit is not strong enough to handle the load from the blower and the compressor at the same time.

Nissan sentra 1998 air conditioner problem

The problem is most likely one of the following:-

1) Open circuit blower motor series dropping resistor - this resistor module is usually located in the blower motor ducting in the air flow.

2) Faulty fan speed control switch, or poor connection in the associated wiring.

Don't know cost of these items.

Nissan sentra n16 temp. overheating

If all of the things you replaced are working fine I am going to say double check the thermostat. Also make sure your fan is engaging at temp. You cam check by running till warm and then running the AC. If the car does not overheat with the AC on then your fan is not running under normal conditions (with AC off) This can be caused by a couple of different things depending on how the fan is set up.

My heater blower is not working.

Have you checked the fuse . If it's not the fuse then check the fan speed resistor? If the resistor is partially burnt out, you should still have at least one other fan speed. ( In my case I had only the high speed.) The resistor is mounted on the Air box and where the fan wire is connected to. Its behind the glove box and easy to find. Remove the glove box by undoing two hinge pins. Rotate the hinge pins upwards and slide them out. The glove box will drop out and you have access to the resistor. Unplug the wiring connector from the resistor and using a multi tester check the continuity. Replace resistor if faulty. Hope it works for you.
