    Dash lights don't come on. Tried YouTube fixes to no avail. It has come on before just to shut off again.

    I hear the dreadful brake pressurizing sound every few seconds constantly.

    We bought this car not long ago for cheap without carefully diagnosing any issues.

    It's noted to have been driven on a 10.5v triple A battery for quite some time. I'm wondering if that's what caused the electrical systems to fail. After watching a bunch of YouTube videos, am.i correct to think that it's a brake actuator going bad and a combination meter going bad?

    If so, is it worth fixing? It might be too pricey. The car has 120k miles, 2008, and perfect hybrid battery 54mpg+. I left it at a shop, still waiting to hear back.

    Any tips or advice is welcomed.

    Ps. I also know I can diy the combination meter capacitor and even the brake actuator but I have no experience doing large car jobs. (The capacitor change sound is fun but not the actuator).

    You're not supposed to leave it at shops did you replace the 12 volt and get a 12 volt battery instead of a 10 and a half volt? Do you have all the amber lights on dash . For abs . Hearing do not matter

    You can get the dashboard to come back on easily and then if you keep the car awake it won't go to sleep the dash that is . Usually you bring it home and try some stuff first before you haul it off to a shop because you might just get it working at the house . Was driving fine no dash . So if you remember how much gas you had you good
