Electric issue

[aerosmith]

Hello,
Wondering if anyone can shed some light on what could be the problem, i have a 2006 Montana parked in my driveway for about a year, i need to fix the cooling lines, before i can start to drive it again. it was working fine until recently.

the van starts, i can drive it tried to reposition it in the driveway , there is no instrument panel power, zero gauges work., radio does not work, no internal lights work,
the blinker works, and i will have to check the high beams

Have you checked for blown fuses?
Have you checked for damaged wires under the hood from rodents?

The fuses as far as I tested with a multi seem good I don’t see any damaged wires to the eye, I think this happens when my battery died and unused a trickle charger to recharge. I’m reading that at times unhooking the battery works should I even bother

If no fuses are blown in any of the fuse boxes you will have to find a wiring diagram.

i checked majority of the fuses with a multi meter, and all seem to have good continuity, i dont see any broken or raw wires. I have read somewhere, that disconnecting the battery might solve this? havent tried it seems odd. I usually keep this van charged with a trickle charger and start it every week until i can fix cooler lines. everything was working great until the battery died, kid unplugged it by accident. so i let it charge again and it runs, lights and high beams run, the header/ac seem to work the fans work. Instrument Panel does not work. internal lights dont work.radio does not work

You can try disconnecting but would be surprised if it did anything

Had similar problem. Every thing in car went blank. Wouldn’t turn over all electrical out. Battery good, power in the engine fuse block. But, No power to instrument panel fuse block. I reached behind it pushed and wiggled the wiring harness firmly forward into the fuse block... everything started working. I’m guessing corrosion somewhere in the harness or plug. Will pull it apart later.

I’ll try that my car starts just no instrument panel or anything electric inside of the car is working inside lights radio alarm on star nothing but car starts and air bag light apparently lights up

Well folks, what I initially though was corrosion was, but not where I thought. Wife got stuck car wouldn’t start everything dead. She got it running by slamming the passenger door a couple of times. After trouble shooting a couple of hours, I worked my way to the engine compartment. After a while, I discovered 1 of 3 ground wires on the battery connector was loose and corroded. It looked good but when I moved it the car shut down. So the moral of the story is what we learned years ago. Check your battery connections first!
