What should I do if my Jeep Cherokee AC is not working?
Open the low side only valve and allow the charge to build to 30 lbs. on the low side and 150 lbs. on the high side. Listen for the click in the low side switch to turn the compressor on. Shut the valve off if the compressor does not come on.
What happens if the clutch on the AC fails?
No cooling at all In more severe cases, where the switch has completely failed, your AC system will completely cease to blow cold air. Without the cycling switch to activate the compressor’s clutch, the AC system will not be pressurized correctly, and the system will be unable to produce any cold air as a result.
When do you need a compressor in a Jeep Cherokee?
If the compressor makes a lot of noise or the clutch will not engage properly, it also requires a compressor. If the high side is very high and the low side normal or low, the condenser is plugged up and needs to be replaced.
Where is the high side line on a Jeep Cherokee?
Hook up the red (high side) line to the valve on the small line and the blue or low side to the big line. Make sure that the knobs on the gauges are in the off position. The small line from the compressor that goes to the condenser and then to the firewall is the high side hose. This line contains from 200 to 350 lbs. of pressure.
