Cooling fans don't come on when temp gets to 200 but they come on when ac is turned on. have checked everything I can think of and fans don't come on when engine get hot.

your fan comes on when your car reaches required temp but if you turn the ac on it will turn the fan on also but if your fan don't work at normal temp check cooling fan relay or fan motor

There are four relays for the cooling fans .low speed control , medium speed , high speed fan control relay 2 , high speed fan control relay 1, there is also a engine cooling fan resistor .The engine coolant temp. sensor would most likely cause the check engine light to be on . There is also a dual pressure switch , this is for the A/C . The cooling fans will be turned on at 213 degress low speed , high speed at 226 degress . If you had factory scan tool or a professional type you could view coolant temp data in pcm , you could also energize the relays to see if the system is operating normally . There are other repair shops beside dealers

Try installing a jumper across the N/O terminal at the relay socket. Temp sensor in the radiator or in the thermostat housing supplies the signal for the relay the other relay signal is supplied by A/C in on position. both fans will run continuous with A/C on. One fan runs intermittent relative to water temp. Be careful not to blow a head gasket. If you leave the jumpers in place, the fans will stop when the ignition is turned off, save the engine until you isolate the relay signal problem. then simply remove jumpers and reinstall the relays

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.

  Hi,
  
  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.

If it has an electric radiator fan (not AC fan) The radiator fan is not working. Possible coolant sensor or switch.

it could be a possibility that the engine is running at normal temperature but your gauges are telling you that it is running hot the only way to tell is to get a temperature gauge & connect it into the water system somehow to give you an accurate reading or take the vehicle to a radiator repairer & they may be able to do it for you..........hope this helps.....cheers.

i am confused you have not mentioned your problem but it sounds like your engine cooling fan is not working? if so try replacing the cooling temp sending unit located on or near the thermostat housing. in fact disconnect it while engine is running and it should turn fan on in a few seconds.goodluck

completely normal those readings are perfect this car comes with a 195 degree thermostat,210 is fine for stop a go traffic remember a cooling system with the proper amount of coolant in it and under pressure will not overheat till about 240 degrees your in great shape no conerns!!!!!...

IF YOU HAVE A SCANNER, WATCH THE COOLANT TEMP. LET THE ENGINE RUN UNTIL THE FANS COME ON. IF THEY DO. THE SYSTEM IS DESIGNED TO COME ON AT AROUND 228 DEGREES.
