If this all started after jumping the battery, then we could just have a weak battery issue.

So, before we go too far let's have the battery checked using this guide to help with this:

Once we know if the battery is okay, we can go from there.

However, if the battery is fine then we need to use this wiring diagram to work through the issue with one of the systems that is not working and if that fixes all of them, then great. If not, we will work through to the next.

Let's start with the seats.

Let's check the power coming from the fuse box and if you have none then the fuse box itself may be the issue.

Please see the wiring diagram below and let us know what you find, and we can go from there.

Thanks
