I have a 2000 with 19K miles on it. It was the dealer's show car, they showed it off at shopping malls, universities, etc. That is why it does not have many miles. Last week the IMA light came on and the dealer read code P1447. So I am now waiting for a new Battery, MCM and BCM.
This morning it started with the 12V starter and now the A/C does not cool. Would the operation of the A/C compressor have to do with the failure of the 144V battery?
During my trip to work (aprox. 30 miles), there was the usual morning battery level drop and force charge, that has been going on since I bought the car 3 weeks ago. After a couple of miles, the battery charged and the assit worked fine, but the A/C did not cool.
Thanks in advance.

Problem resolved! :D
I tried to verify what was going on yesterday, and to my surprise the compressor started and the A/C is back to normal.
My guess is that the A/C compressor must have a trip mechanism that does not allow for it to start if the 144V battery is almost dead. Does anyone have the electrical troubleshooting manual that can verify this?
Thanks
