SOURCE: 1994 Hyundai Excel Air conditioning RADIATOR´S FAN works always very fast

this not really a problem as the fan speed is controlled by the high preasure switch in the ac system the hotter it is outside the higher the preassure will be in the system as hot as its been the preasure is high already when the compressor cycles it pulls suction on one side and outputs high preasure on the other the fans cool the condenser the higher the ambient temp the faster they go so all is fine...

MIKE.
#1) YOU PROBEBLY HAVE A BAD BLOWER MOTOR OR POSS. A BURNT CONNECTION @ THE MOTOR. IF THE FAN WORKS ON ALL SPEEDS EVEN INTERMITTENTLY. THEN THE BLOWER RESISTOR IS OK WICH CONTROLLS THE VOLTAGE TO THE MOTOR TO GET THE DIFFERENT SPEEDS. WHEN THE RESISTOR BURNS OUT THE FAN JUST WON'T WORK ON CERTAIN SPEEDS. THE "RELAY" IS ONLY USED FOR HI-SPEED FAN USE. TRY HITTING THE MOTOR WHEN YOU GET IT NOT TO WORK AND IF IT STARTS THN YOU HAVE A BAD MOTOR.

#2) THE NOISE YOU HEAR WHEN TURNING THE IGN. ON AND OFF IS PROBABLY THE DEFROST DOOR CONTROLL ACTUATOR/MOTOR WICH HAS A POTENTIOMETER IN IT THAT TELLS IT WHEN TO STOP MOVING AS IT REACHES THE CORRECT POSITION. WHEN YOU TURN THE KEY OFF IT BY FEDERAL LAW HAS TO RETURN TO THE DEFROST POSITION IN CASE OF FAILURE. THE LITTLE SPLINES IN THE MOTOR OR ON THE SHAFT CAN GET STRIPPED WHEN THIS HAPPENS. TRY DUPLICATING THE NOISE BY SELECTING THE DEFROST ON AND OFF WITH THE KEY ON.
I WILL CHECK FOR YOUR FEEDBACK LATER

SOURCE: air condition fan only works on high speed, no low speed

You have a bad blower motor resistor. This is located under the dash close to the blower motor itself

SOURCE: Renault Clio Sport 182 Air Con and fan blower fault

I also have a 53 clio with climate control and the fan stopped working. After being quoted £104 by dealership I decided to have a go myself. Bonnet up, remove driverside scuttle cover. Unplug fan resistor 7701051272 (large plug with black wire to fan)remove securing screws and resistor. Dismantled casing and peeled away gel from soldered side of circuit board around mosfet transistor-desolder and remove. Mine was a N342AD 75344G but the nearest I could get was HUF75337P3 from Maplin £1.68. This was the wrong 'package size' but I managed.Close the clamp slightly (before)to hold transistor firmly and then insert transistor and solder. Reassemble. After I got an email from a scrappy QUOTING £20 if you don't fancy the messing about.

Where is the radiator fan relay in 1995 cherokee 4.0L inline 6


most 93 to 95 have viscus clutch not electric fan (A/C evap fan sure) but some do have the Aux fan too. and the PCM reports DTC errors, if the relay fails. did it? report that?
ok the 95 XJ with 4.0 does have fan.... have FSM in hand.
If the ECT has air pockets it well never report hot temps.
it will not energize the Fan relay if the ECT fibs. for any reasons.
page 35 Chapter 7
the viscous fan locksup at (165° to 180° F).
the electric fan is as follows.
i guess you never looked in the PDC before or its lables
"The fan is controlled by the cooling
fan relay, which is located in the power distribution
center (PDC). For the location of relay within
the PDC (Fig. 41), refer to the label on PDC cover"
and now AUX Fan , quote2.
"When coolant temperature is above 88°C (190°F),
the powertrain control module (PCM) provides a
ground path for the fan relay. This ground is provided
through pin/connector #31 of the PCM 60-way
connector. Battery voltage is then applied to the fan
through the relay. When coolant temperature is below
88°C (190°F), the PCM opens the ground path to
the relay. This will prevent the cooling fan from being
energized.
Whenever the air conditioning is operated, the
PCM engages the auxiliary cooling fan


given these facts? why not turn on A/C and end the guessing.

I use my scan tool , and innova 3140 for jeep OBD1.
it shows me what he pcm sees for ECT readings
if the engine is at 100C and the ECT shows way lower
its bad. or has air pockets around it,
no ect runs in air and works, none,.
if say the ECT is at 100C and the fan relay is not closed
the relay is bad or ECU driver to it blown. (bad ecu)
if the relay coil is hot, and the fan is not the relay is bad.

if the relay is closed and 12vdc out of it, then fan is dead.
if the fan is good (hot wired), and the relay out is hot , the wires are bad from relay to fan.
a $10 voltmeter and the guessing ends.

Why i lost engine power after i change fuel filter on MITSUBISHI DELICA turbo diesel L400 2001 model?


check for air in the fuel system
If you did not bleed the system after replacing the filter that will be a fair bet.

SUZUKI SX 2009 FAN FOR AIR CONDITION IS NOT WORKING


times 2, what fan................/?????? point to it or name it... (exact location)
answering for front grill, condenser fan.
cab fan is called blower.
are you a tech>? do you want just wild blind guessing?
no , own a $10 volt meter, well that is easy to use. (1hr, training)

if there is 12vdc to the fan up in grill. then the fan is bad.
if 0v the relay is either bad or being told not to energize.
if the relay coil is 0v (across it)
then the relay is commanded off for due cause.
more tests.. ask.

there are 8 reasons for the (BRAINS box) to cut fan. up to 8.
if the brain box goes to cut A.C
it cuts the compressor and fan.
we can find this easy with that same meter.
in a jiffy.
but most here , just want blind guessing
so here , ill feed the flames.
the fan relay is bad.
ask me tomorrow
and the fan is bad....

My heater/air conditioning fan stopped blowing. Checked fuses, they are fine. No power to fan.


cooling fan relay could be bad,check relay by making a fuse jumper wire.look at the relay control circuits on relay look for control circuits terminal number 85 and terminal 86 hook fuse jumper wire terminal 85 on relay to good ground and take terminal 86 on relay hook up a jumper wire touch battery positive terminal relay should click if not, relay bad.

My air conditioning won't turn off


Could be a stuck relay, but its probably the control panel on the dash.
Is the compressor and fan both running in the off position ?

Why are the fans not coming on in my 1999 deville


99 Deville - have you checked the large fan fuse(s) under and behind the main fuse/relay box ?? (I think this holds for 99 - 2000+ moved the maxi-fuses to the underhood box on the passenger side.)

Also, are your relays on a mount down near the fans ? Some have had trouble with the wiring/sockets there. 2000 or later moved the relays up to the fuse box itself. There are 3 - Fan 1, Fan 2, and a series/parallel (S/P) relay for slow and fast speeds.

Fans run in SLOW at 224 degrees F, FAST at 236 degrees F if there is no air conditioning or DEFROST function set. In the city or heavy traffic the gauge will go to the first tick mark past 12:00 and the fans come on. As the coolant lowers to 213 degrees F the fans turn off and the cycle repeats.

IF you set an air conditioning function, then fans run in SLOW all the time.

If your fans will not run under any conditions, check the large fuses in the underhood fuse/relay box, as well as the small fuses for the fan relays - there are 3 relays: Fan 1, Fan 2, and S/P (series/parallel): the fans are relay set to series operation (voltage drop) for Slow speed, parallel operation (full voltage) for Fast.

1995 grand cherokee limited overheats when the a/c is on


Check the fan operation to the radiator. If the secondary fan doesn't come on it can't dissipate the heat generated from the condensor. There are relays that control the fan under the hood in the electrical center. Check power and ground to both fans when vehicle running A/C on, both fans should be running. Check for blockage in front of rad / condensor.

Fan not blowing on air condition


The fan will not run untill the relay kicks the A/C on.The system is low on freon not allowing the presure switch to close aloowing the relay to power the fan.Add some 134A freon to the system!

Where is the air conditioner blower fan relay on 1996 Jeep Grand Cherokee located?


The blower fan relay is located in the fuse box on the driver's side fender-well. A Jeep Cherokee uses an electric fan as an auxiliary fan for engine cooling and for cooling the air conditioning condenser when the air conditioning is in operation. A radiator temperature-sensing switch that activates the fan relay at 198 degrees F turns the fan on and controls its operation. The temperature drops when the vehicle is in motion and the switch turns the fan off. When the air conditioning system is in operation, the air conditioning relay supplies power to the fan relay via a fan diode downstream from the ignition switch. This diode activates the fan relay and keeps the fan operating as long as the air conditioning is on. Thanks. you can rate this solution and show your appreciation.

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.
