Your A/C needs recharged.

I have a 2003 X type Jaguar and the a/c does not come on when it's 45 degrees outside. Why?
Portable air conditioner will not blow cold air. What to do?

Not likely
if your A/C light is flashing where you adjust temperature and its not blowing cold, try disconnecting the batter for a few minutes, and it will sometimes reset the programming for the air and stop it from flashing, and blow cold, it worked on my 1991 Chevy 2500
about 5 minutes
