The fuse goes hot with the key on, from the fuse it goes to turn flasher, from the flasher to turn signal switch then to turn signals. If you need more info holler.
Turn signals work off a separate flasher. they still did in my 90 Bronco and brother's 88 Ramcharger. Flasher relays are usually on or near the fuse box. Check blower fuse(in fuse box). check the resistor near plug for blower(if charred looking, replace). Check blower by supplying battery voltage to motor(if it spins, it's good)
check the bulbs and sockets they plug into then i would check any ground wires going to or coming from the turn signals i would also check the turn signal switch for any broken parts the hazard flasher is also the same flasher that runs the turn signals so there pretty cheap.
Check fuse # 12 and 14 at the power distribution center (fuse box) in the engine compartment near the battery. If both fuses test good, the the more likely cause of your problem is either the turn signal / hazard switch or the Combination Flasher / Daytime Running Light module. This module is located on the junction block, behind the left side of the dash.
The switch can be tested by accessing the wires at the base of the steering column. Left turn signal = Light Blue / White Right turn signal = Light Blue / Yellow Hazard flasher = Dark Blue / Pink
These wire should show ground when the switch is actuated in its respective positions. If ground is not present when the switch is actuated, check also the black wire at the switch. This wire should show ground at all times. If you do not get ground on this wire than there is an open in this wire. Repair or re-grounding this wire should solve your problem. If the switch test good than the Combo Flasher / DRL module will need to be replaced.
There are 2 seperate flashers 1 for turn signals and 1 for hazard.The hazard flasher is located in the convenance center the turn flasher in the fuse box. Also seperate fuse's for each. One battery circuit for hazard Ignition for turn signals.Check fuse for hazard,if good try swapping in the turn signal flasher and see if hazards work.They use the same flasher unit.
If the fuses are good and the front and rear bulbs are good, change the flasher for the turn signals, even tho the right is working. If that doesn't fix the problem, it might be in the turn sgnal switch on the steering column.
If both bulbs are good for the backup lights and fuses are good, then the backup light switch, which is screwed into the side of the transmission has to bad.
My turn signals worked fine until last night when I ran my battery down and had to get a jump. I realized right away that my turn signals suddenly didn't work. My theory hasn't been tested, but I am going to unhook my battery cables and reconnect again to see if that does anything. If not, I'll check out the steering wheel and that big square thing by the fuses. Thank you for all the posts and I was so happy to find this web page!
