So I have a rear ARB in an 8.25.
When I hit the compressor switch nothing happens.
once I hit the compressor switch & then the locker switch, it starts adding air to engage.

why would the compressor switch all of a sudden not allow the compressor to build before selecting the locker?
a week ago the compressor switch alone would make it turn on without the locker selected.

thank you for any help

Check the wiring from the switch to the compressor. There's probably a loose wire. The locker switch probably always activated both.

8I've checked all plugs/ switches. Connections are solid. Both switches illuminate when activated. Shy of ripping up the carpet and looking at the wires, which I will be doing, the locker us still functioning, But not as it's intended.

I ran power from the stereo when i hooked these up last year. Those connections were soldered and still look good.

Should I be testing for power off of the compressor switch? At the compressor?

Yeah. Check the output at the switch and then at the compressor. Could be that the wire got pinched.

To clarify on the last post the carpet was pulled up and all connections checked. The wiring looks as new as the day I installed it, nothing worn through nor visually pinched.

I've got 12v to the compressor both red wire and red yellow wire. The voltage turns on and off as the comp switch is activated and deactivated.
The power to the Locker switch only engages once the compressor switch has been selected.

Deactivating either switch will purge the compresor.

what should I be checking next, Im still confused as to why the compressor isnt activating from the switch alone?

anyone else have somewhere to steer me in fixing this please and thank you?

Check the switches for input and output current. If there is both, then you probably have a bad ground on the compressor

Ok so the Compressor switch has a constant 12v and when it's activated the output shows 12v. Both a strong 12.31-12.33V.

to check the compressor ground should I be checking from the switch to the ground wire, or ground wire to the body?

if the ground is bad, when the locker is selected, why will the Compressor then turn on?

from compressor to body. When you have a bad ground, electricity will ground itself in funny ways, like when turning other stuff on
