Ok so my 2001, 4.0L Auto TJ was working fine (fine-ish) three days ago. Then my turn signals and emergency flashers stopped working. No clicking, no lights blinking.
Fuse behind the glove box is good, all of the bulbs look good, I just replaced the combo flasher unit (frome the dealership $36.00). Is the four-way switch the next suspect? I initially ruled it out because the brights/dim switch and the dome light piece of the switch works fine.
Is there anything else I can try to isolate the fault to the 4-way switch on the steering wheel column?
1st try working the flasher switch on & off a bunch of times. Often the contacts get dirty from non-use. For the record you have 2 fuses, #13 that you checked is for the signals, #11 in the PDC in front of the battery for the flashers. Since neither work it's not likely the fuses.
OK try fuse 7 that is for 2002 but there can be some crossover.
And "7" was the right fuse in the PDC and it looks good. I changed out the MFS on the column and still not working. I noticed that the male connector on both the turn signal /headlights side and the wiper side of the switch both looked cracked and burnt? Any idea where I can locate replacement male plugs? I've checked Morris and autozone.
OK Thanks for the info. I was assuming I'd cut the the whole bundle and go for it (Using posted wiring diagrams). One wire at a time, got it
OK so new plug is installed. Turn signals and Haz Flshers still not blinking. I did notice last night that when I have the brakelights on and I turn on the turn signal the corresponding brake light goes out. So. . . a short in the wiring??
