1998 Cherokee XJ Air Con Problem
Hi,
I have a 1998 face lift Cherokee, and the Air con does nothing, now it's possible that it needs re-gassing, but there seems to be no change in engine noise when I turn the dial to one of the A/C settings, and I would at least expect the condenser load to show as a blip in RPM or something, can I easily check to see if the condenser is kicking in before I go down to route of getting it re-gassed? Thanks |

You should hear the comressor kick on. If it doesn't you can start the engine, turn on the AC, then temporarily bypass the low side switch. If the comressor turns on then your system is low. The low side switch is on the accumulator. http://revbeergoggles.com/Fixes/sens...essure-low.jpg You just disconnect the harness and jumper the two connections. Do not bypass the switch this for more than a few seconds unless your filling the system. WHen your filling an empty system you bypass the switch so the compressor will suck in the refrigerant. -- DougW |

Doug,
Thanks I did this, and the compressor did kick it, so did the fan, is this normal? I tried topping up the system, and the compressor kicked in & out while doing so, but now it stays off. I only used a top up kit so might not have had enough gas?? Thanks Bryan |
