Wow, sorry to do this but,, was there any resolve to this issue/issues??
I have an 2003 SC F150, with these issues and more.
Things that aren't working;
Power Windows
Moon Roof
Interior front roof console courtesy lights
Hazard Flashers
Turn Signals
OBD Port
Radio Back light
A/C Module back light
Door Ajar bell
Brake not engaged safety feature to release shifter lever
Engine compartment Hood Lamp
A/C blower stuck @ high speed
Probably more, I started crying at this point(Close) like an idiot....

Here's what happened, Engine over heated due too a relay on my E-Fan, my trailer was attached at the time the relay died causing it to over heat.
Water did not go in to engine bay at all, I didn't have to rinse anything off either.
Next day the turn signals started to act sporadically. Changed out Relay #4 to no avail.
Next was to be the Flasher Relay next to the A/C blower relay that resides under the dash next to the console.
I pulled both out to determine which was which, upon figuring that out which it was, I replaced the proper one (Blue) in color and reinserted the other to no avail,,, so I thought....but wait this is where it gets good,,,

Now all the above is going on. Currently detached the battery and charging it to insure a fully charged battery, in hopes it may have been the cause and to re-set the electronics.....

PLEASE HELP

 

Sounds like a General Electronics Module failure to me. You've checked all the fuses right?

 

Yeah that's where I'm at now, I have checked all fuses, breakers, relays etc.... Found one on Flea Bay and made an offer.
Do you know if they require per-programming prior to installation or after. It is a new module so I know/assume it will need some type of programing correct?

Lesson to all, be careful as to what fuses you jumper things off of and as to what load the things one is jumping have and or will draw.........................

 

That is a big nightmare, I wish you the best of luck... sorry I cant offer advice/help but I am not an electrical guru.

 

Thanks, sometimes a best wish can keep a grown man from crying.. :-)

 

For it to knockout all that stuff at once definitely makes me think its ECU or something along thsoe lines. Normally it would just be one thing or maybe a few things tied together... but all of that crap at once is insane.
