110v power outlet dead. All fuses are good.

Help!

My in dash 100v outlet stopped working around 65,000 miles. Until then no problems and I'm not aware of anything unusual happening.

I have always (and only) used it to charge my phone. The USB and cig lighter outlets all work fine and still provide power.

A Chevy dealer looked at it and could not determine the problem. They checked, all fuses were good. Later, I also looked over all the fuses and all good. I pulled the APO/RAP fuses to get a close look. All good.

So, what could be the problem? (Hint, not a fuse.) Anyone else seen this?

Thanks.

Power Inverter went bad? Not sure how but best bet check at the power inverter to verify it has power then I would diagnose the inverter. I wonder if it has its own fuse?

Some inverters do have a fuse as part of the unit-- have you verified that there is 12 volt power to the inverter --??

I don't know how to check for 12v power to the inverter - I don't know where to find the inverter. I've done some googling and best I have found is it's "under the driver side dash" more or less.

I guess I can have Chevy check it at the next oil change.

I'm not 100% but think there's a reset/on under dash.Someone mentioned it because they over powered it.

I don't think so. When the outlet is overpowered it trips a relay that automatically resets when the truck is turned off.
