Hi, the problem you are having could be down to one of a couple of things.
now the first and most likely problem is going to be that your freon level has gone low, this happens over time and all you need to do is get it topped back up and that should then solve your problem.
you can get it topped up at most garages for a small fee.

now the second problem could be that you could have a leak in the air con system, this is very rare but you wont know until you get it topped up whether you have a leak or not.

the chances are if you get it topped back up you should find that this will solve your problem.

let me know how you get on or if you need further assistance ok

    the reason it would come on at the highest level is that its working the pump harder so it might register as having enough gas even though its low, but on the lower settings the pressure would be to low to register so then the light would stay off so getting it topped up will solve your problem because if their was a leak then the pressure would not be their when turned up full so the light coming on at the highest setting then this indicates the system is still under pressure so topping up should solve your problem.

Hi! May i ask when was your last ac maintenance? Maybe now is the time. You may need to replace the dryer, and evaporator cleaning will be great for it may be full of dirt. Try to have your expansion valves checked too... Once cleaned I believe that it'll be cold as it was before. Hope this helps and have a good one!

2001 Nissan xterra temp gauge rises to H when idling?

Dear George,
I'll start with the most common cause.
Check the radiator cooling fan to see if it is functioning correctly.
It is turned on by a sensor that screws into the engine block, and there is also a relay in the under-hood electrical box.
Finally, the electric fan is mounted at the radiator.
There should be 2 fans there, one of them is for engine cooling, one for Air Conditioner cooling.
The engine cooling fan should come on anytime the engine temperature exceeds the setting of the screw-in-the-block sensor.
If it does not, it could be the sensor, the relay, or the cooling fan itself that has failed.
If you live in an area of the country that is prone to extreme cold temperature, "road salt" can contribute to fan failure.
If all these check OK, write us back and tell us, we'll go to step # 2.
God bless your efforts.

Nissan xterra heater

Very low coolant level or a big air bubble in the cooling system. The proper way to fill these is by applying vacuum and drawing in the coolant. Taking it in for a coolant flush should take care of it.

2003 Nissan Xterra - Fan noise when a/c on

No that doesn't sound like the problem, the fan clutch locks up to cool the engine off due to the increased load of the AC system on the cooling system, so it locks up and gets much louder. If it didn't lock up the engine would overheat.

I have a 2007 nissan xterra. When I stop at a light or idle, the heater blows cold air. When I increase the RPM's the heater air warms up again. What could be the problem?

your coolant level is low in the overflow tank/pressure tank. the pressure tank is right by the washer fluid fill cap. its the white tank right behind the washer fill cap, which is blue. make sure you dont open the overflow tank when vehicle is hot. add coonalt into the white tank. you can seethrough the tank. the tank is glued together from 2 sections. lower and upper. you can see the seam when you look at it. fill coolant so its above the seam. that will do it.

You brake master cylinder is either low or faulty. Check your fluid level, if that is good you need to have this repaired as soon as possible as it could lead to brake failure.
