My op manual must be different then yours says that
#1 is 20A fuse Fuel pump
#8 is Horn relay
inside fuse box
#18 is 10A fuse right lo beam
can you give the name for these fuses you listed
these are some of the fuses I already replaced
#24 25A fuse power point
#34 20A fuse trailer tow lamps
#5 20A in the engine fuse module
#2 15A fuse emergency flasher
try number 23 interior fuse what does yours say?
the number 1 is trailor
number 8 is for the multifunction switch
number 18 is all lights and park relay
#23 interior fuse in my book is a 5A fuse insrtument panel illumination
I don't have any fuse in my book that is listed as a multifunction switch
or all lights and park relay.
how do you test a relay?
easiest way is to swap with another other than that you have to flip over the box and see if you are getting power.
Check the light blue wire at the turn signal switch and see if it pulses voltage when you press the turn signal to left or right?
Is it a solid light blue or a light blue with orage srtipe? I don't have my voltmeter so i used my 12 volt light tester. the wires to the flasher caused it to flash.
I checked the solid light blue and got nothing with turn but worked with flashers so i think it is a flasher wire.
the light blue with orange stripe gave me a steady very dim light with turn on or off
there were about four wires that would pulse with the hazard and none with the turn
The plug that has the solid light blue also includes the white w/red stripe (you said is the flasher wire), white w/blue, green w/white, sloid blue all these wires except a sold green one pulse with flashers
so I guess your answer is to replace the switch?
check behind the metal brace and see if there isnt another relay box there
I found a diagram online and it showes the blower / flasher under the drivers dash above the trailer brake control plug. There is a larger Blue relay and a smaller black relay
the one located under the passenger dash on this diagram says RPO relay block?
is this diagram correct for my 97 f150?
OH also I did recheck the one under pass dash could only see the one relay box. It has a small gray relay
Turn signals are now working. I reinstalled the turn signal swicth and It began working agian. Maybe a bad connection with steering column which doesn't make since cause it was working fine before I blew out the fuses.
Also figured out that the fuses and relays in my Op manual are in the same position but are numbered differently then the OP maual I found online at https://www.fleet.ford.com/maintenance/owners_manuals/default.asp
thanks your advice did end up helping in the long run
