I have chased every known problems with the a/c. Still blows hot air. I think it may be the blend door or doors. Can a diagnostic scan tell which is bad? BTW, just finished the dreaded hose under the supercharger. What a pain..Also, changed the supercharger oil. Stunk bad, but sounds a 1000 times better.

 

If on max cool you should definitely get cold air regardless of the doors. If you don't then I believe you've a fault. (Usually the DCCV or if not that then usually the module taken out by a bad DCCV.)

 

After chasing the normal problems associated with hot air blowing from A/C [charge, DCCV, cabin sensors, cabin filter, ambient temp sensor, module upgrade, pinch off the hoses from the DCCV, etc] I went back and read the advice given by JaguarClimateControl.com whose first bit of advice was to check for continuity. It turned out being a broken wire in the harness that lead to the compressor [I believe it was yellow]. Have you checked for continuity on all the circuits and harnesses associated with the A/C system? JaguarClimateControl.com has very detailed instructions on their website on how to do this. It's a bit time consuming and is made much easier if you have an assistant. Good luck.

 

done all the electrical chasing, replacing parts etc. I think the rccm has not been soldered correctly. I will check that this weekend.
