Just a couple weeks ago the air conditioning would blow hot air then cool air then hot air etc.
taking it to shop but sounds like it needs freon. Its a 2011 XJL with 103,000 miles so perhaps a simple matter. Any one else with same issue?

 

No, but then again my 2011 only has 34,131 miles. or one-third your mileage. Freon is difficult to seal, so I suspect this problem is rather normal at your mileage. Let us know how your problem is resolved.

 

Is your problem solved? I had this same issue with a Volvo XC90. Turned out to be a sensor. The sensor that shuts off the compressor keeping it from freezing up. Car would blow cold... freeze up and start blowing hot. I would shut it off... ice would melt... then it would blow cold again.

 

Yes problem solved. Very low tech solution. After having the car for a week and scratching their heads they pulled the cowling cover off the radiator and discovered that the radiator core was plugged with dirt and debris from all the blowing dust in the area. They washed out the radiator core and it runs like a champ. Its like the engine couldn't breath do to the plugged radiator coil.
