Re: ac problem
Need more diagnosis. Have you downloaded the 2000 Factory Service manual?
Someone has PDFed it and you can download it...do a search. I use it all the time.
First thing to check is the AC circuitry: relays, connections, etc..
Then get some gages, maybe the R134A is low so the pressure switches are keeping it from coming on due to low pressure. It is designed that way to prevent damage to the compressor. You might need to jump the compressor clutch to get it going to take a reading.
The AC recharging thing has been covered quite often on this forum.
Sorry, ...just read that yu have a Grand...that is a different forum and is slightly different from the XJ model.
