A/C stopped working and most of the dash trouble lights left side lite up. Corrected a (P0300 code 8 - random/multiple cylinder) all 8 sparkplug coil packs changed, engine running better than normal.
Need additional troubleshooting before I take it to a repair shop.

Rear over head A/C is not working and even the cargo space I believe. but the a/c from the center console for the 2nd row seat is blowing air but not enough to make the back seat comfortable. what might have caused this?
btw. the lights on the knobs for the rear controls are working.
