flakey electric; radio, heated seats, backup radar

Recently I noticed that the heated seats do not work and the light doesn't show on the button. In addition, very frequently, the radio will shutdown restart, also the backup radar proximity lights (at the top of tailgate inside) will all flash. These symptoms all occur at the same time, really frequently now.

I have heard that the relays can be a culprit. Since so many components are bouncing(resetting) at the same time I am thinking it has to be a major bus component, a power relay, fuse, bad ground, etc.

Also the airbag disable would light on the dash. Not sure if it was because my 70 lb daughter was sitting in the pass seat, but that has never happened before.

I don't have a circuit diagram so I'm at a loss to trace the source of this problem. I have changed the ignition switch, not the lock cylinder, to solve the xmas tree dash with success. So that's not likely, imo.

Anyone have any guidance to which distro fuse/relay affects: radio, seats, backup radar ? Would be much appreciated, thanks in advance.

EDIT: adding some more info for ref, I see there is an underhood fusein power distro

F8 40 Amp Green Accessory delay, Seats
from: http://www.wkjeeps.com/wk_fuses.htm#IPM
P'haps I will swap with F12 and see if the prob goes away.

EDIT2: Nope, nothing wrong w Fuse8. Noticing the radio bounces a lot, but backup radar doesn't go crazy as much.
One more item, driving w highbeams on. When this electrical event occurs, my highbeams turn off, lolz. dis is fsck'ed

Wow sounds like you got some crazy electrical problems. I would check your grounds. Weird all those systems would fail at once.

ck grounds clean battery terminals and have it load tested if its more than 4 yrs old you might want to just replace it

Re: flakey electric; radio, heated seats, backup radar

Battery is relatively new, shoulda mentioned that, had an optima yellow top that crapped 1 month beyond warranty. No more optima for me.

I wish I knew where all the grounds were. This seems to be an internal (body) circuit, because all the things that intermittently dump are interior items.

Thanks for the suggestions. I have a copy of the cd svc manual, but for the life of me couldn't get it to run on any new version of explorer. So I have to install a copy of win xp in vmware, what a PITA.

EDIT: Got the FSM working, yes it requires ie 6.

There is a front control module, between the fuse block and the battery that touches many of the interior functions including headlights. This must be the culprit, either it's ground, harness or otherwise. I will try to post some excerpts from the fsm if possible.
