Car Forum / Jeep / April 2005correction to air conditioning question
Sorry - to be more specific, the ac fan kicks in when I turn it on, but I don't hear the AC compressor?? engage, typically where you would hear a "click" and see the temporary drop in the alternator voltage on the Volt meter ect. thanks Turn the AC on go to the compressor and pull the clutch wire you should see it disengage put it back on it should engage. If there is nothing check and see if you have 12 volts at the plug if not check the fuse.

You have to actually lift the hood and look at the compressor cycle on and off. > Sorry - to be more specific, the ac fan kicks in when I turn it on, but > I don't hear the AC compressor?? engage, typically where you would hear > a "click" and see the temporary drop in the alternator voltage on the > Volt meter ect. > > thanks No freon...

What happens it that the o ring seals require constant oil to remain sealed. Sometimes, people don't use it for a long period of time, like all winter,storage, and the seals dry out. Running it for awhile may allow the seals to absorb some oil, and re-seal themselves. This isn't very EPA friendly, but alot cheaper than replacing the compressor or seals. I recomend only attempting this if you know it is the seals that are leaking. I wouldn't keep recharging it hoping it was the seals, but it's the most likely cause as long as no one has tampered with the system, or damaged it. Sometimes it may take a few re-charges. Any more than 3 or 4 and I'd be looking at new parts. Robb |
