Having an issue I can not figure out. My 07 C70 t5 has no AC/Heat, DIM does not work, and information panel does not work. My CCM module is new, my Information Module is new, my CEM is new, and my DIM is new. All installed by Volvo. I did a CAN integrity test and all ohm tests tested good. Just a complete shot in the dark but could it be my ABS module that’s causing these other problems or a grounding problem. If it’s a grounding problem which grounding points should I check? This issue is also draining my battery if I let it sit overnight. I checked voltage when the car was running and it was sitting at 14.2 volts, so the alternator is charging the battery. I also checked the grounds around the left front strut and the three ground points at the bottom of the drivers door and the three ground points on the passenger side on the bottom area by the door under the carpet. Any help would be greatly appreciated.

What my display shows while running. What’s weird is when my battery was low all of a sudden my outside temp and time came on but went off quickly and my gage needles started to bounce.

What the local Volvo dealership already recently replaced. It seems like they were just throwing parts instead of trying to fix the problem.
