89 blinker issues

Need your help! Been neglecting the jeep since kids came along and finally got around to getting it out after basically sitting for two years.
Neither the blinkers or the hazards will work, nor will the indicators on the dash turn on. Also, when I depress the brakes both hazards indicators illuminate?
I checked the 15A signal fuse and it looked fine also swapped out signal flasher with an el-12 without any luck.
Thoughts? Any help is much appreciated!

With the hazards coming on with brake pedal, it sounds like you may have wires shorting across systems. Any chance that there is a trailer plug wired in wrong? That'd be the first place I'd look. If it isn't there it sounds like you have a job ahead of you tracing wires.
Wondering too if a steering wheel got worked on or changed?
What were the last things you did to the rig before storing it?

Check your front and rear signal bulbs. It sounds like you may have a shorted filament.

Also, check ALL your lighting grounds.

Good Luck, L.M.

So ironically enough, hazard indicator lights are no longer coming on with braking. Also, I do not have a trailer plug. To my knowledge, steering wheel is original and I'm only the second owner.
Nothing special before storing, just parked and never got back to it...
Thanks for the insight!

Will do. Hopefully it's only a bulb!
I do have flush mount rear taillights but they were added 10 years ago and never had a problem, anything there?

I like Mac's idea about checking the lamps. While you're in there doing that, check wiring at each lamp. Sitting for 2 years, I wonder if mice or pack rats got in there and messed with wiring harnesses? Had it happen on one of my wife's cars. Only chewed one wire but enough to throw a check engine light. He paid the ultimate price for that one.

283 YJ makes a good point.
Varmints have a way of getting back at us for exterminating their relatives. It's real common to find chewed wires on any vehicle that sits for an extended length of time.
How many of us have found nests on top of a engine or in the air cleaner?

Good Luck, L.M.
