Let me mention that a title of all caps doesn't get a quicker response
Gauges.. any flickers, indications at all or one day totally dead? We need more info.
ECC and AC/Heating issue is probably all lumped into one problem. There'* a good chance it'* an air mix actuator. If you search on that, you'll find tons and tons of info.
CD player, yup.. probably your wiring, please post what you did in the audio section. Pictures help as well.
The hood I would suggest buying locally. Shipping is prohibitive, however the wanted section would be the right place to post for one.
That should get you started..
