And once the cooling cycle is over, the moisture drips off of the coils and into a condensate pan. Just a note here about the steering column. I will tell you from lessons learned from the above steps what you do not have to do, if you don't want to pull the whole dash out and save a little time. Just did my 2011 Fusion. As the switch heats or cools, the shape of the bowl changes activating or deactivating the ac compressor. See if the sensor is either bent away from the coil or makes direct contact. Remove the two instrument panel center brace bolts.
Usually when a tech is checking the system, the leaving temp is what he's looking at. If you suspect that your evaporator temperature switch may be having an issue, have the vehicle diagnosed by a professional technician, such as one from YourMechanic, to determine if your vehicle needs an. Colder coil and shorter cycle time or slightly warmer coil and longer cycle time? My sensor was bad and I could tell by looking at it there was a problem. Any thoughts on this problem? I am still shaking my head when I think about it. Based on that, your sensor is probably open, not shorted.
Had to spend an extra fifteen minutes realigning the steering wheel when it slid off the end during removal of the dash. Thanks everyone for your feedback! Luckily, I was right near my car because he had fell asleep and it was 105 degrees outside. Saved me a bunch of money. You are now ready to remove the console. Remove the weather striping from the front door openings near the instrument panel.
Well, sometimes these sensors short out and will not allow compressor operation. Do this twice on both side of steering wheel so there is no way it can move and make sure the ties are secured to dashboard and steering wheel is set with front wheels pointing straight forward. Special Offer: For a 5% discount on any number of copies of the Home Reference eBook purchased as a single order. Running lower amps longer vs higher amps shorter might be a wash but can save if comfort is maintained. When the temperature drops bellow a preset temperature value the will be turned off, thus stopping the compressor and avoiding damage to it, due to the change in oil viscosity and , because of too low temperature in the system. I did find it unnecessary to remove the steering column and steering wheel.
Sounds like you should not change anything. One thing it also does that makes it seem more efficient is that it removes moisture also. Only during system installation or servicing would we actually pull a true vacuum on the system as part of evacuating it prior to installing a refrigerant charge. Warning sensors on the gauge console are also lit up. Otherwise, the system would freeze. Although we endeavour to ensure that the information contained on the website is accurate, as errors may occur from time to time, customers should verify any information in question with a dealer. If you aren't getting banned once every 3 years, you aren't trying.
Next take out the small section that has the power interface and disconnect the power by depressing a clip. I decided not to let them touch my car again, and just picked up the parts myself. Through a series of levers and gears, the mode door controls the defrost door, the foot door, and the vent door. Whatever part you need for the job, Motorcraft has it. Thank you Ray for providing us with this wonderful forum!!!!! You could check the connection and test the thermistor with an ohmmeter if you have one. The hot, compressed vapor is then discharged to the condenser.
Switch is installed in glove box. Is there an easy way to check whether the air conditioner is working properly? Photos are for illustration purposes only. There may be some variances between the photos shown and the actual product. Colder coil and shorter cycle time or slightly warmer coil and longer cycle time? I prefer using the suction pressure to determine the coil temperature. I do not recommend taking on this project if you don't know what you are doing.
If you are the do-it-yourself kind of person, I will attach the instructions on changing the sensor yourself below. If the pressures are fine then one should consider the possibility of a blend door not functioning correctly. Too high air conditioning output temperatures may indicate that the system is not working properly: perhaps the coil has become blocked solid with ice. If your comment is not related, it will be deleted. This information is very useful. Fred, your instructions were very helpful. The sensor tells the computer what the air's temperature is at the exit point of the evaporator.
A 37 kOhm resistor will generate a signal equivalent to 20 Celsius and avoid the compressor to shut down. That can mean higher technician productivity, higher customer satisfaction and potentially greater profits for your business. I checked the relay and the relay is good because I replaced that. Next turn on your key and shift the shifter into 3. Again I can't thank you enough for the efforts in posting this!! This code will reset automatically after replacing the sensor or in some cases a scan tool will be needed for this purpose. I don't know the color code of the wires for the sensor.
Well, as moisture collects on those cold refrigerant coils it quickly turns to ice, eventually leading to a completely frozen over coil. Typically this temperature drop is 15 to 20 deg. I live in Boynton Beach by the way. If is doing either, both can be the source of the problem. Mine blows 34 degree air at 95 degrees.
