One of the first symptoms of a potential problem with the evaporator temperature switch is Another symptom of a problem with the evaporator temperature sensor is fluctuating temperatures from the AC system. Reply Thanks, trying to fix my kids A/C without breaking the bank.What if I put the motorcraft evap temp sensor under the glove box and connect it to pin 13 and 15 will it work instead of the 37 k ohm, so I do not have to worry about freezing the evap or the heater not working. Most auto repairs shops charge between $75 and $150 per hour.

Any ideas?? My pin layout doesnt have a 3rd wire on Thanks for all the info on the ac evaporator sensor problem. 11 months ago

(check here: https://www.youtube.com/watch?v=imnNjh6wGo4).The good resistor is shown on the chart.
It is a part of the vehicle’s AC system, and as its name implies, detects and monitors the temperature of the AC system’s evaporator. Workaround that avoids the replacement of the AC evaporator sensor from all Ford Fusions up to 2012. 1 year ago A 37 kOhm resistor will generate a signal equivalent to 20 Celsius and avoid the compressor to shut down.
6 weeks ago Therefore, it is not cheap.Disassembly of the glove box pressing it on both sides.Pay attention to the left connector (it may be green or blue - normally green).Wires BU-BN (blue/brown) and VT-BN (violet/brown) are the wires connected to the temperature sensor (thermistor). If the evaporator temperature sensor sends an incorrect or erratic signal to the computer, it can cause the AC temperature to behave erratically. $3 instead of $900 to Ford! I can’t find a wiring diagram that identifies the two pins used by the sensor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. 2 years ago My ac is now putting out 57 degrees and 43 on ac max. Cost of diagnosing the P0538 2012 FORD FUSION code Labor: 1.0 The cost of diagnosing the P0538 2012 FORD FUSION code is 1.0 hour of labor. 1 year ago When using AC on very cold days, the evaporator may ice, in this case you have only to shut the AC off and let the ventilation working.There are three good youtube videos showing the dashboard disassembly.Longest service time video following Ford instructions (by the book):I have a 2012 ford fusion SE with a blue connector. If this is your case, the wires must be chopped off in order to guarantee the good resistance measurement. Works fine cost less than 3 bucks Answer But heater blows ouside air temp, so I installed a DPDT switch so that in winter it will be hooked to evaporator senser and flip switch in summer to read through resistor. I put the resistor in to fix the ac problem and read a post that someone lost the heater after doing so. Reply
