Fox Guys Need Electrical/Wiring Help!!!

[Lunch Box]

Okay

is there anything wiring wise that the
-Reverse Lights
-Turning Signals
-Rear Defroster

share in common?

Why?

-When i first got the car all three worked in unison and all three would not work in unison. meaning if 1 worked all worked 1 one did not work none worked

Finally they have officially stopped being intermittent and now completely do not work...

I have a couple wiring diagrams but can't seem to find anthing in common with the 3 (i suck at wiring)

Little back round info to help you guys maybe recognize a source of the problem

I would have to shake the turn signal lever for a bit to get it to work, same with the rear defroster button id have to keep pushing it

Somtimes if i got the rear defroster on (at this point i knew turn signal would go on) as soon as i turn the signals the rear defroster would make a click noise and turn off... and after toying with it i could get it to stay on

Also when the signal was on... it blinked painfully SLOW

To correct this i have
-replaced every fuse
-new Flasher for both hazard and signals
-hunted down wires for countless hours resulting in me getting NO WHERE lol

I have heard possibly the multifunction switch

but i have a diagram that i been using and it doesn't show the defroster or reverse lights on it.

What year car is this?? Each year is slightly different. I have some diagrams but they may not apply

Are you sure fuse 5 is ok?

If your HVAC fan also doesnt work, the ignition switch might be on the outs (

Has the ignition switch (the electrical connector) been replaced recently? The ig switch is still a possibility as being the problem.
Good luck.

The HVAC fan being the thing that blows air when i turn the AC/Heat Knob around then yes it stopped working as well. I have had hte car 3 months and i have not replaced the ignition switch.

That's a sign of a bad ignition switch. They're 20 bucks from Ford and take 20 mins to replace. I'd do this, even if on the off-chance it's not the issue, because the switches are a wear item and it's nice to have a fresh one.

Otherwise it will take some circuit testing to narrow down the issue further.

Good luck.

well i did my ignition switch today and of course it did not fix any of the above problems

my HVAC motor still dead
Signals still don't work
Rear Defroster still doesn't work
and my reverse lights STILL do not work.

finally fixed it... idk how but the brand new fuse i had in there was melted.. popped another one in its been working fine for hte past week now

but hte HVAC motor still not working

 

[facemelter71]

Does the motor only work on high,or not at all??If it works on high then its the blower motor relay in front of the fan by the passengers chins.If it doesnt work at all,its the fan itself.

i had it disconnected for a while cuz i was installing a system and to make it easier i took the control panel out of the console. hopefully i reconnected everything the right way...


but it doesn't turn on at all
