2006 Blowing hot air no AC

It got warm recently, so turned my AC on, was just blowing hot air, although the compressor was kicking on and off, so I put some Freon in, no change. I could feel heat below the dash that told me hot water was running through the heater core/system. Found a JAG AC web site, (DIY: Diagnose It Yourself - JaguarClimateControl.com) has a procedure for checking the sensors, DCCV, and CCM, oh boy, here we go. Knowing the DCCV can corrode and lock up, I took a shovel handle I had cut off a broken shovel, and poked/banged the DCCV from above several times, just to see what might happen. Drove the car yesterday, and whataya know, the AC is working! No heat below the dash.

Boeing has a similar procedure for the air conditioning packs on certain planes. A compressor/turbine unit would not always spin up properly. Boeing gave very specific instructions about where to hit, and even suggested using a tire chock. Also works like a charm.
Back to your DCCV, I'd suggest planning to change it in the near future. If sticking like that, it is likely to eventually get worse. The 2003+ cars also have a nasty tendency to burn up the control module, too.
