First of all there is a temp sensor and a fan switch,on the motor.Call the parts store. Follow the wire harness from the sensor. Back about eight inchs pull the wire out of the plastic see if they are broken.

    ah ha! turns out there is a coolant fan switch also. This switch is located at the bottom of the radiator passenger side. After checking both fans, fuse, heat sensor coming from the block under the disributer, relay switch located under and attached to the bracket that holds up water over flow, there was still the coolant fan switch located at the bottom of radiator passenger side. after replacing it everything worked great...finally... Troulble was Most all the help I got up to this point did not mention theis switch,,It was the least expensive part of the three I purchased.. the toughest to diagnose as a problem because wasn't able to get a signal of continuity cold. Probably could have changed it first without the other fixes..end of story, fans both come on when they are suppose to now, no more over heating and I have replaced the several vital parts to the cooling system with new. Since all the parts were old I am happy to have replaced them all. total under $100.00

SOURCE: Acura MDX A/C won't come on

I went to an Acura dealer to buy the transistor for the rear A/C unit. The service advisor told me that the problem with the front A/C was probably due to a defective front transistor / resistor. I bought that part too.

The front transistor is located next to the blower motor under the dash on the passenger's side. It is secured by three or four small bolts. The one on the bottom left is very close to the carpet and the most difficult to get off and put back on.

The rear transistor is located behind the carpeted trim panel on the center console (driver's side). The carpeted trim panel is secured by clips only - there are no screws, so remove it carefully starting at the side near the accellerator pedal. Once the panel has been removed, reach inside a small hole in the metal frame to access the rear transistor. It is removed by twisting it and pulling it out. The hole in the frame is small and you might find pliers helpful.

After replacing both parts, the front and rear A/C are working. Apparently these transistors are common failures. If the A/C is out in your Acura MDX and the fuse checks good, a new transistor will likely solve your problem.

SOURCE: engine cooling fans not working

if relays are good its most likely the engine coolant temp switch

SOURCE: radiator cooling fan not turning on

I would follow the wiring from the fan to the engine. There should be a temperature switch that controls an electrical circuit based on engine metal and coolant temperature. It controls the cooling fan, temp light or guage, fuel mixture, emission controls, and ECU functions. It is usually brass or stainless steel and is threaded to go into the engine block.

SOURCE: cooling fan wont come on when suposed to, i

Ive run into this a few times,you have a bad coolant fan sensor, this car uses two one operates the fans when the key is off and the other operates them when the car is running, theres one sensor in the front cooling housing and the other on the rear housing, replace the other coolant sensor and that will solve your problem, take note theres two sensors on that rear housing one for the fan and one for the computer. hope this helps.

SOURCE: how do you replace the relay on the cooling

it may not be the relay but the cooling fan itself failing intermittently, I had the same
problem with an 04 PT cruzer and the fan was intermittently failing (if the fan has an open frame on the motor water gets into the motor). I replaced the relay with no success
(located in the engine compartment as yours will most likely be). Once I replaced the
fan itself, the problem went away and the A/C functioned much better. Hope this helps.

Engine coolant fan wont come on. The fan motor is fine. whats next?


You still have many other components in that system that has to be in working order for the cooling fan to work properly. The cooling fan is turned on when engine temp reaches a predetermined temp, usually around 220-230 degrees F. the ECT (engine coolant temp) sensor siganls the ECM (Engine Control Module) to ground the cooling fan relay or cooling fan module(if equipped) and if the cooling fan fuse is good and the fan has power to it the realy will complete the ground for the fan to run. You may need to have a qualified technician diagnose the problem if the obvious things like fuses and good grounds are not the problem.

Hope this helps.

Fan not working...my car is overheating


The fuses are located in the fuse box under the hood, but could be the fan motor too, check if you have power at the motor

Cooling fan does not come on


This is controlled by a cooling fan sensor/temperature sensor, as well as fuses, and a relay. These will have to be checked.

Make sure your coolant level is full, the coolant temperature switch won't work if the level is too low. If coolant is low, you need to find out where it went to by pressure testing the cooling system.

If it's not low and the fuses are good, the relay is working:

The fan should be tested, bypassing any sensors to make sure it is functioning properly.

The sensors can be tested to be sure they are working properly at the correct temperature with a voltmeter/ohm meter.

Reverse troubleshooting the wiring and ignition is the next step if you haven't found the problem.

Good luck !

Check the cooling fan fuse,and relay,if they seem to be fine,make sure the fan is good,and change the coolant sensor,and see that there is enough coolant in the system and the thermostat has been changed,and there is no air in the coolant system,bleed it out.

Fan motor is good checked it with a jumper wire to positve my guess is the sensor where is it located


If it is a cooling fan motor,then it can be a cooling fan relay,or fuse,that is bad,or the coolant sensor is bad.Make sure the cooling system is bled of all air.If it has air in the system,the coolant sensor will not work.

Is there a cooling fan fuse?


Everything in car is fused. The fans are controlled by a thermal sensor. You will need a wiring diagram to test for a faulty sensor.
