Check to see if the capacitor is good. It is usually located inside the outdoor unit. It could be that the capacitor is bad and needs replacing. The outdoor fan will still run if you have a dual capacitor. One sure sign of a blown capacitor is that the top of the capacitor is bowed outward. If you have a multimeter you could also check the amp draw on the condensing unit. I would look at the capacitor first though
When you turn on the AC, check to see if the compressor is running. If the compressor clutch is not engaging, it might be as simple as low refrigerant level. Automobile AC is not like a home AC. Since the compressor cannot be sealed, the seal always leaks a little and you need to occasionally add a little refrigerant.
Can't do it. The lubricant is mixed in with the refrigerant. Converted to air it would be running dry.
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
Mabe your compressor is not kicking on for some reason. Check to see if the front of your compressor starts spinning when you turn it on. If it don't check to see if there is power to the wires that go to your compressor. If there is power you have a bad compressor. If there is not check the fuses or relays.
check fuse or relay in underhood fuse box,
Could be your ac compressor is going or gone, probably gone.
You have a cycling clutch compressor. Turn the AC on max, let the car for five minutes or so, go look at the compressor. You should see the clutch engaging and disengaging the compressor as the pressure builds and drops.
No fan-electrical Fan/no cold-check refrigerant. Refrigerant ok, check compressor.
Running the AC compressor uses horsepower, and the truck does not have enough to overcome the loss.
There are several things that can cause your air conditioning compressor to turn off after five seconds. The most common cause is a lack of Freon pressure. Check your air conditioning hoses for a leak.
If you want it constantly running jumper the high pressure cut off switch wire. And if you dont want it running turn off the ac. If pully is seized see if a napa can get a shorter belt to route around the ac compressor
If the clutch on the AC compressor has seized, the engine can in some situations stop running. The compressor could be bad but it is also possible that the clutch only is bad.
