A/C Compressor - problem isolated, but not fixed
#21
No problem European Steve, the pressure switch is an inexpensive part and at least now we've ruled it out as the problem.
The tech believes that everything is happening correctly UNTIL the point when the ECM is supposed to signal the compressor to come on...and that signal isn't coming.
Not a good time for no a/c...the southeastern United States is coming under a heat wave today and temperatures will rise to above 100 farenheit for the next few days. Thankful that I have a bulletproof Honda as my back-up....same year as the Jag and never, ever fails me in any way, lol.

I should say adding Freon. I could only measure low pressure with the gauge that came with the Freon can. It was in the range prescribed in charts available on this post at the ambient temp....in this case 35 or so at 80 degrees. The compressor now seems to click on/off...let out some freon below the prescribed chart pressure at less clicking on off of compressor.

As someone else mentioned in this thread, Do a complete service to the a/c system. A complete evacuation held at negative 30 psi for at least an hour. The reason for that time is to boil out any moisture in the system. Keeping in mid that both moisture and air are condensable and will create pressures that seem normal but will not produce cold air.Then recharge with virgin r-134 to spec. If the system has been charged with diy cans you may have an excessive oil charge in the system that can have a major impact on system performance. Also never use gas that has a sealer in it. I would do this before I start throwing parts at it.
Good luck

Hi. I did get a replacement pressure switch and had this fitted whilst getting a load more workdone underneath and when done the air con is still not working. That's the 3rd attempt now and I'm starting to despair with it.
Need to find somewhere that really understands this issue and car and get it done,. Preferably without getting a large bill, seeing as I've already spent probably £500 on this issue.
Any ideas for people down South of UK would be appreciated
