Has two relays fan hi an fan low . did you see that ? ECT sensor - engine coolant temp sensor is a input to the ECM - engine control module . The ECM monitors the coolant temp . when the temp reaches a set temp. the ECM will energize the fan on low speed by suppling a ground .If the sensor ECT was bad would have a check engine light on an a codes set. Your best bet would be to have a qualified repair shop check it out .Hook up a scan tool .

SOURCE: Need the Location of the temperature sensor on 95 olds cutlass.

The image isn't loading, so I can't tell if this has been 100% answered, but here's the text version:

Should be a fuse panel under the hood, passenger side near the coolant tank and radiator inlet. In that panel should be 2 large square fuses. These are fuse/relay combo deals. Switching these out should fix you right up. Mine had the same problem about a month ago and I had to replace them then.

SOURCE: Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: can't locate the cooling fan sensor or relay.

the radiator fan relay is located behind and slightly lower than the r/f headlamp.best way to get to this is by removing right side of front fascia out enough to get behind it. this will give you acsess to the relay.i work at a jeep dealer and have done this many times.

I have a 2007 jeep grand cherokee that the cooling fan wont come on, I replaced the fan relays,temperature sensor and cooling fan .

Did you check the fuse and the voltage at the supply side of the relays? How about the wiring and particularly the connectors? Also, it is not unusual for a new temperature sensor to be faulty - try jumping the contacts in the sensor connector to see if the fans activate.

I have a 2010 chevy aveo. The signal relay for the turn signal clicks constantly when not using the flashers or the blinkers. I replaced the relay and it still clicks. not sure what is causing this.

It may be a grounding problem in the wiring.. probably the turn signal switch that is located inside the steering column..These switches have plastic parts that can crack and close a circuit. You need a dealer repair as there are various sensors and sensitive wiring inside the column that controls deployment of the air bag.

My 2010 Chevrolet Aveo LT is making a clicking sound when I turn on my AC, but I turn it off it stops- occassionally blowing cool air but then turning hot. Any suggestion for an easy fix without breaking...

Your system is low on R134....the clicking is the compressor engaging and disengaging. You will get cool air while compressor is on, then warm when its off. They will act this way when R134 is low. Now either a leak in the system, or the system just needs a boost. Another thing to check is the condensor fan under the hood.When you turn the AC on,the condensor fan needs to be running, if its not then its a bad fan motor,relay, or fan sensor. I don;t know what your abilities are, but maybe armed with this info you can work on it yourself, or at least not get taken advantage of at the mechanics. Good luck !!

98 Honda civic cx over heating when stopped in traffic - I went thru cooling system, replaced hoses, thermostat, fan, radiator cap. After that stated to overheat on freeway after about 40 miles. pulled...

Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

How do you check a cooling fan that wont run on 2002 grand cherokee

ELECTRIC Cooling Fans are Controled By
1) Coolant temp Sensor

Use DIRECT CURRENT AT the FAN PLUG<< +POS & --NEG FROM BATTERY ONE BRIGHT COLORED WIRE at FAN PLUG is +POS. the Other is --Neg If the Fan COMES ON then your Problem IS BEFORE the FAN @ ONE of the 3 OTHER COMPONENTS ABOVE

Cooling fans will not come on

Hi,

Fan Relay switch is stuck open. This of course assumes your temperature sensor is working appropriately. Which I assumed since you seem to know that the engine is running hot.

Replace the fan relay switch. The relay switch is tripped when the temperature sensor tells the computer the engine is too hot.

Until you get the relay switch replaced, you can either by-pass the relay switch and directly connect the fans to the battery, or turn on your A/C ALL the time and use it at a minimum setting. This will keep the cooling fans running at all times.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Cooling fans dont engage! 1998 oldsmobile silhouette!

Your Problem Can VERY WELL BE with the Temp Sensor, As It Is the First in This Electrucal Circut . it Waits for 210-230 Degree Engine temp and Gives that Sygnal to the ECM then ECM Grounds out the Cooling FAN RELAY To Turn ON the FANS and the Temp Sensor is Usualy THE #1 Culpret Closley in front of the RELAY.
There are 2 Sensors On this Vehicle The One You Replaced and One Located At Trans Side of
Engine Closer to Front of Vehicle At the Head ,Thereis a 2 wire Plug On it and This Sensor Goes to the ECT witch CONTROLS COOLING FAN RELAY. Hope this Helps and if you Need A Diagram For this It Must be Emailed as FixYa Does NOT Support Large Picture Files. My Email Add. Is MY
