I have a problem if anyone could help me. I have an 04 f-250 6.0 diesel king ranch. The turn signal will not come on at all. The hazards work and so do the lights and brakes lights. As well as the windshield wipers. I have replaced the relay behind the radio and also the signal switch assembly as well. Checked all fuses and all are fine. Is there another relay and if so where is it located? Just trying to narrow all options before bringing it into the dealership.
i have the owners manual and have checked all fuses and relay. I did replace the multifunction switch if you are referring to the switch attached to the steering column that turns on your wipers and high beams yes. The wiring inside the steering column looks normal checked it all over and see no wires that may be cut or anything wrong with them. Now today as i started my truck the ac will only blow air from defrost vents. Are these two things in conjunction or do i now have 2 different problems.
so once again I am trying to figure out this signal light why it will not work. I have already Done all of the above and in addition to i have check the voltage and i am getting 12 volts On the blue and green line that connect to the multi-function switch. Any help that anyone can assist me with this please i would appreciate it.
One thing that would help you would be the wiring
diagram for your truck. Not the junk one that can
be found in the Hanys/Chiltons manuals. Because
they tend to not be that good and reliable . You
want the Ford Shop copy.
