Hi:
The compressor clutch wire goes to the pressure switch , which is often located on the side of the evaporator, or in the line going to the evaporator. When there is enough system pressure, the switch has continuity, and if the system is low or empty, the switch is open, to prevent the compressor from running . If your system is fully charged, you can probably guess the switch is bad, but most likely your AC system is low on refridgerant, and keeping the compressor from running.
hope this helps!

My 01 toyota corolla le radiator fans wont work


Using a test light connect the lid to NEGATIVE and start the engine with A/C on.back probe the positive terminal on the fan.If no power test the fuse. if fuse OK switch the relay with the horn relay and test again. if you have a power to the fan connector switch the test light lid to POSITIVE on you battery and test for good ground to the fan.some times ground wire can corrode and create a lot of problems. If you have good Power and Ground replace the fan.
good luck

Coiling fan radiator


Having a problem with the electric fan? Here's what to check: first make sure fan is free-wheeling. Spin it by hand. If no obstructions, use jumper leads off the battery to test fan motor. If nothing, motor is bad. If fan operates off the battery, find the radiator fan relay under the hood, and pull it out. One relay terminal will have a hot at all times power source, probably from a fuse link or a maxi-fuse in the fuse/relay box. Check that one terminal is hot at all times, using a voltmeter or test light. If you have air conditioning, turn the AC on, key on. Now, two terminals at relay should show power-the power feed source, and the signal from computer to turn the relay on.
Didn't say what kind of car or year you have, but here is how an older Nissan turns the fan on, without using the computer, and with no AC: the relay signal to shoot power to the fan comes from a thermal switch mounted in the radiator. When coolant reaches 194 degrees F., the thermal switch will close contacts internally, passing power to the relay's coil side of relay. Relay is energized and passes power to the fan motor.
For your car, you will have to check a wiring diagram to see how the cooling fan circuit is set up. The fan relay may be triggered by the computer or by a coolant sensor somewhere in the coolant system.

My 1991 isuzu trooper heater blower fan is not working, nor when i turn it to the airconditioner the compressor does not engage. i checked all the fuses except the ac relay fuse block, what could the...


if the lower fan speeds dont work but the fastest speed does the heater fan resistor block needs replacing. If the highest fan speed doesnt work leave it on there and check for power at heater blower fan, if power is on one wire and the other is an earth the blower motor fan needs replacing. Use a normal globe test light to check this. If no power on any wires to fan go back and check all fuses in car and under bonnet with same test light. If fuses are ok possible open circuit wire to fan.

YOUR a/c compressor is cut on by the vehicle pcm(computer).pcm sends a signal to a/c relay to energize relay which sends power to compressor. Have you checke dall the fuses with a test light? last dodge i worked on had a blown horn fuse which powered a/c system also. block said nothing about this. here is a diagram999f7d5.gif

Hello,

I have a 2003 Chevy Cavalier. The HVAC airflow dial only works on high setting. We checked the fuse and it's o.k.

What now?  Any estimate as to repair cost? 

Thank you

Blower motor will not work


Do further tests at the relay to ascertain whether the fault lies before or after the relay.
Check power availability at the supply side of the relay contacts - should have 12v from a supply fuse on one side of the normally open contact (note -this supply may only be available when Ign or Acc sw is on).
If power supply is ok at the relay contact, check control input to relay operate coil.

If a ground (or 12v) operates the relay, operate the relay with a local ground (or 12v) and check blower motor runs.

If all above OK, check control signal from fan switch is arriving at the relay control coil.- if not trace wiring back to the switch.

My radiator fan does not work under any conditions, all fuses ok, wondering which relay is it to check conditions, thanks


Here are the cooling system diagnostic steps...First does the cooling fan kick on (with engine hot)? If not, check the fuse, if good then check the thermoswitch in the radiator (it's about an inch and a half in diameter located on the lower part of the radiator with two wires ) by disconnecting the wires and touching them together (again, with engine hot...at least 190 degrees) if the fan comes on, you have a bad switch. If not connect a 10 gauge jumper wire from the battery to the fan itself (there are three terminals,,, one high, one low and ground). With power direct from the battery (and a ground wire, if necessary) fan should run... if not replace the fan assembly... if it does run then you have a bad cooling fan relay. It will be located above the fuses on the fuse block... Hope this helps...;-)

Radiator fan


You should check the 30 amp "RDI" fuse and the 7.5 ECU-IG fuse. Both fuses are critical to the operation of the fan system. The RDI fuse sends power to the fan #1 relay. The A/C amplifier turns on power to the fan #1 relay, this is why your fan works on A/C.

Now, with no cooling fan under "normal conditions" (A/C off), you need to have a good fan #2 relay, and a good water temp switch. This switch is on the engine, near the thermostat housing (I think); with a single plug, with a white with a blue trace wire going to it. Remove this wire from the sender, and jump it to ground (anywhere on the metal of the engine) with the key on (engine OFF). If the fan starts, you need a new water temp sending unit. If not, then consider a new fan #2 relay. This system is pretty simple.
