my last thread got close and this link was posted by a mod https://g35driver.com/forums/audio-v...epair-diy.html

i have read this thread before the issue and looked at it again. the ac is not blowing and the temperature and compass display all stop working after i heard an spark. now from my research ive seen that if the radio/ac control goes out the ac still blows but you cant change the temp. if the above link is my proble i should at least get the compass on the display. the radio still works. any help is appreciated

I'd check for blown fuses, but as far as repairing what may have caused the fuse to blow, the previous linked thread is the only thing that'll give you worthwhile help.
