Look into the turn signal switch itself. Have the wiring checked.

When it does not crank, check to see if voltage is getting to the starter. If it is, hit the starter. If it starts , replace it.

When you say the jeep will not turn over, you mean that it will not crank? If that is so then you may have a bad starter or coolant may have filled a cylinder with water. Pull out the spark plugs and see if it will crank over, check to see if water comes out of the heads when cranking. If it still does not turn over, check the starter.

Unfortunately, the relay may be located inside the transmission. Try utube if you have not already.

You don't need to go by auto zone to have codes check ! Chrysler , Dodge and jeep vehicle's can be checked without a scanner ! Turn the key on then off then back on then off again an then on an leave it on . Check in the odometer an it will show P codes ,then it will show done !
What size engine does it have ? 4.0 or 4.7 L
Fuse #17 10 amp located in the junction block powers pin #16 at the DLC . This would power up a scan tool . Not a PCM fuse !
Your vehicle does not have a separate control module for the transmission ,it is part of the PCM - powertrain control module !
Jeep vehicles with stalling an idle going high then low ( surging ) is caused most of the time by a bad TPS - throttle position sensor ! An don't use one from the aftermarket , use factory parts !

If you think that faulty brakes are OK then fine, keep driving it without looking to find the issue.
If you have ABS, suspect the ABS controller under the brake pump.
