2005 Rubicon. When I put it on 4-low and lock the rear diff the front locks also. Indicator light is solid. I press it again and the front Indicator stays blinking. What would cause my front to lock when I only press the switch once?
 
Likely your wires are crossed down at the lockers, go underneath and switch them, should fix your issue.

Edit: It could also be the air lines are swapped. Off hand I can't remember if the plugs are the same so if they don't swap, then just swap the air lines. Both air compressors are identical.

Not the air or pumps. I only had front jacked up so I guess I need to put all 4 tires off the ground to verify rear isn't engaging
 
So long as I interpret your question correctly, the first time you engage the lockers your front locker dash light is illuminating? If that's the case, go down under the Jeep where the lockers are. The easiest fix is to swap the main airline coming out of the lockers. I remember the plugs for each locker are different colors, but I can't remember if they are interchangeable so the airlines might be the easiest fix since the first press merely tells one of the lockers to pump up. Your dash illumination is generated inside the diff when loop is closed from the air pressure.

If both rear and front lockers are engaging with one push of the switch, then you might have a bad locker switch.

Is this the switch you are referring to?

When you push the button once, are the rear light and the front light solid?

Are both the front and rear actually locked?

Does the front or rear light blink after the ignition is turned off?

Going to get all 4 tires off the ground now. Give me a minute
 
Either the air lines or the wires were swapped.

I asked which wires and got no reply. That's why I ignored the response. All I see under there is a plug which I posted a picture of and still got no response. So could you help me out with a picture of the wires you are referring to?
 
Not at the axles. At the compressors on the skid. I would assume they just swapped the air lines, as the connectors are keyed IIRC.

The electrical connectors are keyed and cannot be swapped unless they are modified.

That is my picture of my Rubicon air pumps relocated to the ABS tray, btw. 🤫
