So I just bought an 04 avalanche and I'm having a parasitic drain. I am not a good car person to be clear. I got the truck and after a few days it started to turn over slower and progressed over the next few days till it was too low to start. I got it jumped and drove it for a couple hours and it started afterwards so the alte re bator is charging it. I usually only drive about 45 min a day just to and from work. I brought it to the shop and he tested the battery and it was good just low charge. He also waited till it was in sleep mode and got a parasitic drain of 17 milla amps or whatever and that is within the "acceptable" range. He charged my battery and after a few days the same thing happens, it's slow to turn over. My abs light is on and he tried to communicate with it and it wasn't responding so he says it's the ans control module. Could that cause my drain to be excessive before it gets to sleep mode? Maybe a relay that's moody? The radio also seems to be in muted mode? It plays just not very loud at all and basically no base. The sub is in the center council and I put my hand on it and you can feel a slight vibration from the sound and it's more than I get from my hand on the panel under the steering wheel. Could that be the amp? And could that be somehow tied to my drain issue?
