Question about 2004 Nissan XTerra

1 Answer

The AC quit working (out of the blue in the middle of driving home)... The thing is that the compressor is still active, but when I hook a gauge up to the low-side port for re-charging, it tells me that it is almost 2x the pressure required (110-150... different EVERYTIME i plug it in). The AC is on it's highest setting, ambient temperature is 95*F, I've re-charged other vehicles enough to not have an issue knowing the difference between the low and high side ports... what is up?

Check the condensing fans?
But it sounds like the orifice right at the evaporator is bad but if the high side is low and the low is high then the compressor is bad,

Ac quit work after turn on


You can try doing a coolant recharge, go to your local auto parts supply and get a can of refrigerant. Follow the instructions on the can. You have to locate the high pressure valve on the system don't worry the hose only fits on the right one. If all goes well hook it up start the engine and turn on the AC to high. Once the gauge reads charged you should see the compressor turning and you should have cold air.

My ac system is blowing hot air, how can i fix it?


You need to know how an ac system works to make repairs.
It could be an electrical problem, low on freon, or a mechanical problem with the compressor.
A mechanic would check for power to the compressor and the freon charge with a gauge set.
Freon is minus 30 degrees coming out of the can.

Ac intermittently quits working, just replaced condenser, put dye in system at mechanics- no leaks


Have an AC repair shop hook up a set of AC pressure gauges while this is happening to see what is going on. You could have a defective AC compressor or a low refrigerant charge in the system. And as to the hot weather causing it to act up that would be normal, the AC would cool fine the cooler the outside air is, problems like worn out compressors and low system refrigerant charge levels would only show there ugly head in hot weather conditions. Also make sure the cooling fans fo rthe AC and engine are working properly. Good luck with this.

When i turn on the a/c,the compressor does not work


CHECK REFRIGERANT CHARGE. USING A MANIFOLD GAUGE SET. HOOK MANIFOLD GAUGE SET TO LOW PRESSURE PORT AND HIGH PRESSURE SIDE PORT. LOW SIDE PRESSURE SIDE SHOULD HAVE 25 - 36 PSI AND HIGH PRESSURE SIDE SHOULD BE 178 - 237 PSI. IF LOW SIDE PRESSURE SIDE READ BELOW 20 PSI THE LOW PRESSURE SWITCH WILL NOT TURN ON THE AC COMPRESSOR CLUTCH NEED TO ADD LITTLE MORE REFRIGERANT. IF REFRIGERANT LEVEL CORRECT CHECK AC COMPRESSOR FUSE AND RELAY.IF POWER GOING TO AC COMPRESSOR CLUTCH YOUR COMPRESSOR CLUTCH HAS OPEN WINDING. AC COMPRESSOR CLUTCH NEED REPLACING.

HIGH PRESSURE SIDE GAUGE SHOULD 199 - 228 PSI. THATS NORMAL CHARGE. SEE YOU CANT JUST RECHARGE AC SYSTEM UNTIL YOU CHECK IT FIRST YOU WILL DAMAGE SYSTEM .NOW YOU CAN GO TO AUTO ZONE PARTS BUY A CHARGE CAN WITH GAUGE AND HOSE.ATTACH TO IT.YOU NEED MORE THAN ONE CAN.WARNING MAKE COMPRESSOR IS RUNNING WHEN YOU TURN ON AC .BECAUSE IF COMPRESSOR NOT RUNNING CHECK FUSE AND AC COMPRESSOR RELAY.IF BOTH OKAY.YOU COULD HAVE OPEN CLUTCH COIL A FAULTY LOW PRESSURE SWITCH WILL CAUSE AC NOT TO WORK. IF LOW PRESSURE GAUGE BLUE SIDE PRESSURE IS 28 OR 30 YOU DONT NEED A CHARGE.PROBLEM SOME WHERE ELSE.BE SURE TO WEAR SAFETY GLASSES WHEN WORKING ON AC SYSTEM.

1996 toyota tercel air conditioner will not work


Hello, and welcome to FixYa. Let us try to help.

Yes, you read correctly; if the refrigerant charge is low,or the refrigerant has leaked out, the AC compressor will not activate. Pressure switches built into the system inturupt the power to the AC clutch if there is insufficient system pressure.

I would suggest taking the vehicle to a qualified garage, and have the service tech there hook his set of 'AC Gauges" to the car. After he does that, he can tell you if you need a partial charge, of if you system is empty. I would def recommend the car be checked with the AC gauges; as adding refrigerant to the system without knowing how much is currently in it can damage the compressor.

Thanks for choosing FixYa for advice!

AC booster recharge hook-up


You can only attach the the recharge hose from the kit to the low side ( A/C service port) and the cap should be blue with a leter L on it. Good luck and follow the instruction and don't over charge the system. With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the R134a and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood.  Good luck and hope this helps.

Intermittent cold air on a 2001 Grand Am GT (3400 engine)


When you say tinker with the A/C. what did he do??? Just want to make sure he did not hot wire anything to activate the compressor at the max position. If the system is low on compressor oil the compressor will not active to keep it from getting damage or low on R143A. Most place now will recharge the A/C system for $50.00 since they know that you can by a recharge kit for around the same price, but you need make sure you don't over charge the system or damage will occur. If you not familiar with the recharge procedure, have it recharged by a shop and if it's full then the problem may be a  pressure switch and that takes around 5 min to replace and i am sure the shop will let you know before they try to recharge the system by hooking up the gauges to read the pressure in the system. Good luck and keep me posted, be glad to help you get some cold air again.
