What does it mean when the compressor kicks on and off?
Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems. Several conditions cause short cycling, including a faulty or obstructed thermostat, leaking refrigerant, icy coils or an HVAC system that is too big for the building in which it is installed.
Why is the a / C CLUTCH not engaging in my Ford Ranger?
The A/C requires a enough pressure on the low side to engage the clutch. It protects itself in the event there isn’t enough R134. Put a gauge on the low side (the side nearest the coolant overflow/washer bottle) and see where it’s at.
What should low side pressure be on Ford Ranger?
See the Ford Ranger troubleshooting charts in here: ( http://imgur.com/a/xMUKH ). Notice the chart says low-side pressure should be between 20-50 psi, which means the compressor should shut off at 50 psi, and turn on at 20 psi. Your low-side (blue cap) pressure is rather high.
How to bypass a switch on a Ford Ranger?
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. See electrical schematic in lower right corner of this: http://i.imgur.com/7bJyuXd.png
Where does clutch fluid leak in Ford Ranger?
Problem: There’s a leak or bad seal in the hydraulics that’s big enough to allow air in. Fix: Clutch fluid can only leak from three places: master cylinder, slave cylinder, lines. Check at the firewall where the master is mounted for signs of leaking first. This will indicate a bad master cylinder seal. Check along the lines as well.
Are there any problems with the new Ford Ranger?
Common complaints from reviewers and consumers on the new models include a stiff ride and lackluster materials used in the interior, which to some appear dated. If you’re in a market for an older Ranger, here are some issues that you need to know about.

What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.
