How to find out if your Ford Ranger has an AC problem?
How to find out if your Ford Ranger has an AC problem?
See if the compressor clutch is spinning. Test power at the compressor. (should make the light come on) If you have power at the field coil wire, take a screwdriver or something and kind of smack the clutch (assuming it’s not spinning) into the pulley and see if it engages and starts running…or at least “clicks” some, even if it quits again.
Why is my AC compressor not coming on?
Compressor not coming on As the pressure switches control the on/off function of the AC compressor, a switch failure can prevent the AC compressor from functioning at all. The compressor is what pumps refrigerant through the entire system. If it is not functioning, then the system can not operate, and will be unable to produce cold air.
What to do if your Ford Ranger stops running?
If you have power at the field coil wire, take a screwdriver or something and kind of smack the clutch (assuming it’s not spinning) into the pulley and see if it engages and starts running…or at least “clicks” some, even if it quits again. That’s an indication you have a bad field coil behind the pulley.
What happens when a pressure switch fails on an AC compressor?
3. Compressor not coming on. As the pressure switches control the on/off function of the AC compressor, a switch failure can prevent the AC compressor from functioning at all. The compressor is what pumps refrigerant through the entire system. If it is not functioning, then the system can not operate, and will be unable to produce cold air.
Why is my air conditioner not working on my Ford Ranger?

Why does my Ford a / C compressor keep running?
If the coolant is brown, and rusty with a lot of sediment then the chance are good. Sounds good, thanks. The a/c compressor even runs in vent mode. The only way to shut it down is to turn the whole system off. Still seems wierd why Ford would keep it on for all modes.
How can I test my Ford Ranger AC?
it shows the high and low pressure switches in series to a ground then in to the pcm. when the switch opens the pcm shuts the ground off for the relay. you’re going to have to test for power at the power side of the ac clutch relay. if you have no power you’re going to have to start testing the high and low pressure switches.
What to do if your Ford Ranger has no power?
you’re going to have to test for power at the power side of the ac clutch relay. if you have no power you’re going to have to start testing the high and low pressure switches. if you had a gauge set it could be easier to diagnose. Thanks for the link to the wiring diagram.
Why is my air conditioner compressor not getting power?
No power to AC Compressor Clutch. Here are the details: After researching this I’m thinking it could be the relay in the CCRM (constant control module)?
Where is the low side pressure switch on a Ford Ranger?
The low-side pressure switch is only 1 of 3 switches (OK, 1 of those is a relay) that need to work before the compressor clutch gets power. You can bypass a switch with a paperclip CAREFULLY shoved into the rear of the switch connector, or unplug it and shove the paperclip into the front of the connector.

Is there a bad a / C pressure switch shutting off the compressor?
Put 12 volts to the compressor and make sure the clutch locks up first. You checked the compressor clutch fuse, right? Highly unlikely the ECM died for the a/c only. Is there a bad a/c pressure switch shutting off the compressor? Get a shop to hook up the manifold gauges, jump the compressor to engage it and read the pressures.
How to know if your air conditioner is losing power?
Here is a guide and the wiring diagrams for the air conditioner system so we can see how it works. Check fuse 10 – 10 amp for power that is what feeds the low pressure switch and see where you are losing power. Check out the diagrams (Below). Please let us know what happens.
Is the AC compressor on a Western Star working?
Discussion in ‘ Western Star Forum ‘ started by 04 LowMax, Jul 7, 2014 . Wondered if anyone has done any trouble shooting for this problem on a star?

Why does my AC a / C CLUTCH keep turning off?
It seems that sometimes it decides to start blowing slightly colder air while other times it just blows hot air. After taking it to Pep Boy’s for diagnostics. It turned out to be a relay. Once relay was repaired it turned out that I overcharged the system.
When does the compressor clutch kick on and off?

Why is my a / C not putting out cold air?
The A/C on my 2004 Ford Freestar is not putting out cold air. The compressor is kicking on and off. What could be the problem? The compressor turning off immediately is usually a sign of a safety mechanism kicking in.
When does the a / C CLUTCH turn on and off?
When I turn on a/c the clutch turns on and off constantly in 2 second cycles- 2 seconds will engage then 2 seconds will disengage. It is fully charged (used gauge), obviously I can’t get the best reading because clutch goes in and out, but when engaged it goes up to the proper area. Video Player is loading. This is a modal window.
Why does the compressor clutch kick on and off randomly?
The compressor clutch kicks on and off randomly during the…. The problem could be from a partially clogged orifice tube. It may restrict refrigerant flow too much, and the high side has time to climb too high (and low side draw too low). Then either the low side or high side switch could cut power to the compressor.
What to do if your Ford F250 has an air gap?

Why is my car air conditioner cycling on and off?
I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went. Everywhere I turned, people said that if the compressor was cycling on and off quickly, that meant the compressor was low on freon.
