1996 XJS air conditioner stopped working
Folks,
As always thanks for allowing me to share my issues. Just today here in sunny hot!!!!!Venice, FL I took the CAT our for a ride.
So hot..turned on the air conditioner and it worked beautifully as always....
Never had any issues with the air conditioner system.
Got to my destination parked the car returned about 2- 1/2 hrs. later to return home. Turned on the air conditioner but got nothing but HOT AIR!!!!!
It didn't sound like the compressor kicked on??
Most likely issue:
1. Hopefully just a fuse/relay??......Where is the potential culprit? Engine compartment or inside the vehicle...Can't tell from my Service manual. Looked in the general help section but couldn't find anything.
It was really hot ~93 degree's.
Any ideas are appreciated.
Thanks
Paul

The compressor is not kicking on!! Checked the relay and it seems to be clicking in and out when power applied offline.
It does not look like there is any freon in the site glass which is hard to believe as it was running perfectly. I have some freon and when I connected the can to the system the gauge went immediately to high pressure at the maximum reading.
Can someone explain what this is indicating?
Thanks

Did a little more and found the 5A fuse under the passenger side panel. It was blown.
Put in a new fuse turned on the system and started to feel cold air. The fuse then blew again.
So, now it is narrowed down to something is causing the compressor clutch from staying engaged.
Again noticed that the Pressure on the refrigerant was extremely high when I tried to connect a new can of freon.
Any ideas?
Thanks

By overfilling thensystem, you're more than likelymto cause more damage.
Get the system filled correctly. Means vacume, refil, new oil.
The reason the fuse blows? Too much draw from the magnetic clutch can cause the fuse to blow. That is probably the only part that causes the fuse to blow, unless the Delanair is a lottle wonky... But that shouldn't be the case.

When I attached the freon to the low side?? the gauge immediately was in the red zone 80-100 range.
I'm not 100% sure that the clutch was engaged and the compressor was still running.
What are some of the typical things that would cause the clutch to keep kicking out.
If the pressure shows high and the clutch kicks in but has too much to push against is that why it is blowing.
Could this mean something is plugged.
It does not look like there is any freon looking through the site gauge.
Vee, Any suggestions, ideas are appreciated.

I have always filled the system with the engine running so that the compressor can function properly.
I never refilled the system because the moment I attached the fitting to the fill side and it registered over pressure. So I did not try to put any freon in.
Here is the question:
What kind of issue can cause the clutch fuse to keep blowing??
1. Is something plugged up causing the high pressure.
2. Is the compressor gone bad and leaked not allowing the system to be refilled.
3. Some kind of bad valve
Your responses are appreciated!!
Thanks

By filling it with the engine running you are increasing the pressure in the system. When the high pressure side has a higher pressure, you trigger the switch. That is why properly filled, you use the high AND low pressure connectors.
What fuse did you replace? What was it 'called' (what fuse number on which fuse panel?)? Doesn't have to be the compressor causing the problem. It will be something drawing too much current...
