Either the gas is low or their is pressure sensor switch somewhere on the system and this could be faulty ,telling the system that there is no gas pressure so shutting off the feed to the compressor ,another posibility that i often get is a faulty switch on the dash but as the fans come on then i do think this rules this one out,another way around it is too run a feed from the switch to relay supply for the fan ,then to the ac motor which effectivly by passes the safety switch as a temporary measure because the vehicle will need to be put on a proper AC machine to empty the gas so a new sensor switch can be fitted ,then vacumn the AC and then the correct weight of gas added to the system

Car runs hot when idling

Make sure the electric cooling fan(s) for the radiator are working.
TEST- anytime the air conditioning compressor kicks in, so should the cooling fans. Locate the a/c compressor on the engine, it's belt driven. Start the car and with the engine running observe the face of the belt pully on the compressor while an assistant turns on the a/c in the car (defrost feature on your heater control will also cycle on the compressor). You'll be looking to see that the front of the compressor pully starts spinning when the a/c or defrost is engaged. When that pully starts spinning the radiator fans are supposed turn on at the same time. If you see the compressor engage but the fan doesn't you have a blown cooing fan fuse, bad fan motor or a bad fan motor relay. If there is something wrong that your compressor isn't engaging in a/c or defrost and the fuses are ok, you're going to have to check the fan motor and relay by different means. You can disconnect the wiring plug to the fan motor. This is where you see if you can spin the fan blades by hand. It should spin very easily. If it is hard to spin or is siezed up, you found the problem. If the blades spin easily- direct jump current to the fan motor off the battery. If the fan doesn't work, replace it. If the fan works, check the relay. Locate the fan relay and look for another relay in the panel that is EXACTLY like it. WE WANT- another relay that is exactly the same BUT NOT critical for engine or a/c operation. We also want to know that whatever feature this candidate relay supplies power to is verified as functional. Swap the relays. If the fan still doesn't engage, check the function that you borrowed the relay from and verify THAT works with your original a/c relay in it. If you lost that function, try the proceedure with a 3rd relay if possible. Again check and recheck functions you borrowed the relay from. If you still get nothing, put the relays back to original placement. If you still are getting nothing from the fan and the other 2 functions, then the panel is toasting relays and you need either run the problem down or get the car into a professional. Now- if the fan won't engage but the other functions that you borrowed relay(s) from are still operational, we're going to give the relays a passing grade and it would seem you've got an electrical issue that, again, you need to run down or defer your efforts to a professional. Good luck on your endeavor.

Compressor and fans do not turn on until rev engine

I passed this question the first time I read it, so I will take a stab at it now.
The fans don't come on until the compressor has pumped the freon pressure up to say 150 or 200 psi. And the compressor clutch has to have voltage to engage the clutch.
I wonder if the clutch is going and needs 14 volts instead of 12 to engage ? Or the relay that powers the clutch ?
Speeding up the engine would increase voltage from the alternator.
This is assuming the serpentine belt is tight and everything else is working correctly.
I think I would swap the relay with another and put a meter on that circuit to the ac clutch to see what it takes to engage it.

Cooling system fan don't come on

  • Improve the FixYa experience for everyone by voting. I want you to let me know if the solution(s) suggested were of any value. Constructive criticism is welcomed.


    I'm Ben and -- hopefully -- I can provide some meaningful assistance.
  • Check if it is getting power. Check fuse No. 34.
  • Check the cooling fan relay.
  • Run engine to bring temp up then turn off engine, disconnect harness,Visually inspect for pinched wires.
  • Test for power with a test light(have to turn ignition on).
  • If you have power could be a faulty fan (try spinning it to jump start it and see if it takes off).
  • No power could be a faulty sensor or bad wiring.
  • My experience with this type of problem points towards a malfunctioning temp switch if everything has checked out at this point.
  • It's located at lower cooling house, bottom right.
  • To Test that you need to bridge or jump the terminals. If you hold the terminal with the fastener on top and flat side left.
  • Test for power first, Ignition on
  • Left side female controls 1st speed jump them and see if fan works.
  • Right side female controls 2nd speed jump them and see if fan works.
  • If your fan works replace the Temp switch if not. and you do have power check out the fans.
  • if you don't have power chase the wires back looking for a broken, burnt or pinched line.

A/C Compressor won't turn on Can jump compressor from battery and compressor comes on & cools. Hi pressure switch checks out ok and 12 volts going to hi pressure switch no voltage to compressor

the high pressure switch kicks the compressor off when the pressure rises, the low pressure switch kicks it on, check that switch, unplug the wire and use a continuity meter to see if the switch functions, also check for power getting to the plug itself

To add 134a, which of three wires on the pressure switch should I jump to get the compressor to run to add freon?

you don't need to jump the wires. even if the compressor clutch is not turning add the refrigerant to the low side port, it will go in through its own pressure when a safe level for the compressor to run has been reached the clutch will engage. at first the clutch will spin a second or two and stop and then begin again, from there continue adding refrigerant the clutch should spin continuously. if the clutch fails to ever engage the compressor is bad or there is a wiring problem.

How do I make the AC compressor turn on to fill the freon when it is empty?

Find the low pressure switch and unplug it and take a wire and connect both wires together tying the circuit together this should automatically turn the compressor on. Make sure the switches inside are on high maximum blow and A/c switch is on. You could also run a wire fused directly to the wire going to the head of the compressor. Usually once you start putting freon in as long as everything is working perfectly it should automatically kick in with jumping it over or putting direct power to it.

Charged a/c system no leaks compressor would not kick on held 30 minute vaccuum checked for leaks replaced condensor due to hitting a coon could not find low pressure switch to jump to kick compressor on

turn ac on with engine running check for power at the compressor if there isnt check for power at the low pressure switch if there is jump out the connection
the compressor should turn on the low pressure switch is usually located on the accumulator canister (SILVERY CANISTER) near the firewall.

Temp fan failure could be the thermo temperature sensor. I am not sure of the actual name of it but if you can direct wire your fan and it works, then the fan is good, the sensor is bad. I myself have rewired a switch to them so I can control when and how long the electric fan runs.

I have a 99 Jeep Grand Cherokee, that is running hot, cooling fan is not working has a ground doesn't have power. If I jump it out the fan works. What controls the power?

I have the same problem with my 99. I am going to try to jump it to test if it's the fan itself that's dead, which I doubt it is. If it works when I try to hard wire it then it's either the fan fuse, the fan relay or the temperature sensor that is bad. I am thinking I have a bad temp sensor which is what tells the fan to kick on when the coolant is warming up. If my fan works when hard wired then I am going to jump it off one of the fuses that is only on when the vehicle is running. I don't think it will hurt anything to always have the fan running while the car is running.

2004 PT Cruiser radiator fan comes on in high speed mode when AND

You can either jump power from the high to low sides, or wire a switchable power wire so it comes on when the ignition turns on. It isn't really computer controlled. A sensor just sends power to it when it needs to run. No fear of hurting anything.
