No problem Fred. I have not looked into it yet but it will be soon. I will need the a/c!

 

Wanted to bring you up to date on my A/C. It was the 4 way pressure switch as you all suggested.

 

I have spent many hours trying to find an answer to the question On a 1997 XK8, can I replace the air conditioner pressure switch without losing my freon charge?". Does anyone have the definitive answer?
Thanks in advance for any help! I think this is the most useful forum I have ever found!!!

No! That switch in measuring the system pressure.

 

97-xk8: Have replaced compressor, receiver/dryer and now pressure switch; still no A/C. After replacing pressure switch, the engine will stall after being at idle a short time when A/C is turned on. Jag Dealer Tech ran diagnostics and thinks it is the Climate Control Module? - $1200. new. They want $400 to run Pinout test to prove if it is Air CCM or not. I am thinking about finding a used/reman. CCM or at least a better price for new and putting it on myself (might have Jag put it on if reasonable price to install?). Any advice as to whether this is a good idea? Thanks in advance for any help you may give me; my better half's temper is rising with the rising temperatures here. It is beginning to get hot here - Mississipi, near Memphis, TN.

Got home tonight and noticed a drip, drip, drip from under the car. Not good, as like humans, I prefer all the fluids on my car on the inside.
Got a tray under there pronto and took a test of the fluid dripping out of a tube half-way down the underside of my Jag. Clear and odourless. Ok. Had the A/C topped up yesterday, so hoping this is just an enthusiastic mechanic with a heavy hand. However, still dripping an hour later.

I'm new in here guys, so go easy on me, ok? Driving my dream and don't want it to turn into a nightmare.....

Cheers

 

As this is your first post, may I suggest you drop into the new member section and post a introduction.

As for leak, you may just find that it is nothing more than condensation flowing from the drains. Quite normal and also proves that your condensate drains are clear.

Hope this helps,

 

Perfectly normal - it's the condensate drain - shows the system is working. Be more of a worry if no dripping water

 

Paul, two questions 1999 XK8 4.0 with intermittent A/C, pressures are good when the clutch is working and it may work for an hour, then fail, and work the next day for another hour.
1. When the A/C is not working how can I bypass the pressure switch to verify that is actually the fault?
2. If it is, do I have to vacuum the system to replace the switch or is there a Schrader valve below it?
