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
