Where was the AC EVAP temp sensor replaced?

Turns out the AC evap temp sensor had to be replaced behind the dash. Under warranty I had Ford replace it. Well it wasn’t a week later and the AC compressor wasn’t coming on again. I took it back for a second time and they replaced it again. They said the first replacement was defective.

What does 37 KOHM resistor on Ford Fusion do?

How long does it take cold air to turn hot in a Ford Fusion?

When it’s cool outside, the ac runs forever. But in hot weather, it might blow cold air from 5 seconds to 5 minutes. In super hot weather it’s not even worth trying. Maybe 10 seconds max. I can turn the car off and something resets and it will blow cold air again until it switches back to hot. Na donce it switches to hot it stays there.

Why is the a / C not turning on on my Ford Fusion?

But on the Fusion, if the A/C compressor is not turning on, you will need to change the Evaporator Discharge Air Temperature Sensor. The sensor tells the computer what the air’s temperature is at the exit point of the evaporator. When it senses that it’s cold, it turns off the compressor.

How do you install a compressor on a Ford Fusion?

Remove the three instrument panel cowl side upper bolts. To install, tighten to 23 Nm (17 lb-ft). CAUTION: To avoid an improper connection at the bulkhead electrical connector, be sure to position the connector for installation then push the release handle to the full DOWNWARD position until it clicks.

Once you’ve removed the old sensor, the replacement steps are in direct opposite order. The first step in the installation process will be to reattach the electrical harness to the new sensor. Step 10: Reinstall the EVAP temperature sensor. Screw the new sensor into the AC condenser, turning it to the right.

Can a temperature sensor be replaced on a Ford Focus?

However, the job itself of replacing the sensor is incredibly simple (once the dashboard has been removed).Common vehicles that experience failure of this component frequently include the Ford Focus from 2003 to 2008; however, it can fail on any vehicle over a period of time.

Why does my Ford Fusion a / C compressor not turn on?

The sensor tells the computer what the air’s temperature is at the exit point of the evaporator. When it senses that it’s cold, it turns off the compressor. Otherwise, the system would freeze. Well, sometimes these sensors short out and will not allow compressor operation. Ford is well aware that the sensors are faulty.

Read reviews of repair shops in your area. Enter your zip code:

Is there a problem with the EVAP temp sensor?

The wife took it by Ford for an oil change and asked about running an AC test and told them that the evap temp sensor had been replaced. The tech said that it could be a bad upper or lower compressor sensor. From what I’ve read, this will result in a 200 buck repair that doesn’t fix the problem.

How does the temperature sensor work on an evaporator?

When the sensor detects that the temperature is approaching high temperatures, the AC system will increase flow through the system to increase cooling and will reduce flow when it detects that the evaporator is cold to conserve power and prevent it from freezing over.
