What could be causing these to stop?
These all stop working at once (with no warnings that i can hear/smell/etc) - AC/Vent/Heater blower, front wipers, turn signals, radio, cigarette lighter.
Rear wipers still work, and headlights & inside lights still work.
All will come back on together - randomly. But are staying off, now, for the most part.
Any idea what could be causing this?
Thank you!

most likely your ignition switch located under the dash above the pedals on top of the steering column, i had one that was burnt out and with a lot of the same symptons.

Thank you very much for the help all!!
I was going to change it today but it's raining pretty good now.
So will wait until it's over.
------------------------------
I researched what you sent me and found that the steering column needs to be dropped, for it sits on top of it (as in picture above).
What i found is to remove bottom dash panel (and disconnect any wires that keep it from coming off), then remove 4 bolts to drop steering column. Then 2 bolts to remove ignition switch.
Am i missing anything?
Thank you!

yes thats right. i believe there is one more small bolt that holds the highbeam switch in place and if i remember right that has to come lose as well.

Thank you all!!
The ignition switch fixed my issues.
---------------------------------------------
Advance Auto sold me a faulty ignition switch so i had to go back and get a second one. It would not crank after replacing 1st switch.
But after replacing the second switch, not only did my blower/turn signals/wipers/radio/cigarette lighter come back on, it cranked as well.
Thank you so much!
-----------------------------------------------
I did notice a square box mounted to my lower dash (under glove compartment). When the cable harness was unplugged from it i had no acceleration. Jeep would barely move.
What is that box?

Concerning the ignition switch replacement:
I noticed, today, that i have to turn the key all the way til i can't anymore to get it to crank. Then it cranks right away. One time i couldn't get it to crank.
It's like i need to be able to turn key a little more.
Would this be due to the actuator rod not being in the correct switch position (Lock, Accessory, On) ?
If so could you tell me the correct position it should be in?

Thank you much!

i looked at the old switch and you can see about where in which position it was screwed down by looking at the marks from the screws, when you install the new switch and keep that around the same position you can pretty close for the right adjustment but its also a bit of a touch its doable takes a bit of time. glad you found your culprit.

that box under the dash on the passenger side is your transmission control unit, or TCU. it's the computer for the transmission. with it unplugged, it will try to start in 3rd gear. you can however shift it manually from 1st to 3rd, but will not have a 2nd, since 1st and 2nd are shared on the shift lever.
