The problem with the AC in the Ford F250 is pretty common. The symptom is easy to notice: the AC starts working intermittently. It blows the cold air and then it stops working and blows the hot air inside.
While the problem is not that annoying in winter and other cold seasons, in the summer, you may be really mad when this is happening to your truck. And there are some solutions you may try.
Common reasons for AC working intermittently in the F250
1) Connection problems
There are basically two weak spots - the connection on the AC compressor and the AC switch. Both are located under the hood and are easy to reach. Wiggle the connections with your hand when the AC malfunctions and see if this is the problem.
Those connections may be cured by changing the clamps or just cleaning and maintaining them properly.
2) AC compressor clutch air gap
Old AC compressors in the F250 may develop a large air gap in the clutch system. In some cases, it may be solved by just taking out a shim from under the mounting bolt. In other cases, the compressor clutch should be replaced.
This is pretty common for older trucks but can also develop in newer models.
3) Sensors or switches should be checked
There are several sensors that measure temperature and pressure in the AC system. Those will throw codes if they are not OK, so you may check them with the OBD2 scanner.
Also, the AC switch in the climate control unit may not be working properly. It may send on and off signals intermittently making your AC compressor go on and off. The switch is hard to check on your own.
Also, if this is happening with your newer F250, this may be the problem with the climate control sensors. They may freak out and make the AC turn on and off depending on the current readings.
Is there anything you can do on your own?
Before you take the truck in for an inspection and repair, there are several things you may want to try:
- reset the truck by disconnecting the battery for several minutes - this will let you deal with minor software issues and control module failures;
- try resetting the climate control if you have the automatic control feature in your truck;
- check the connections by just wiggling them with your hand and see if the problem disappears;
- use the scanner to see if there are some fault codes connected to numerous sensors in your vehicle.
If nothing helps, I believe it's worth taking your truck to the dealership or to the trusted independent repair shop.
