2003 Low Pressure Service Port

I can't find it, I'm just about to say it doesn't have one and forget about recharging it. Any Help

From the FSM:

The high pressure service port is located on the refrigerant line, near the discharge port of the compressor.
The low pressure service port is located on the liquid line at the rear of the engine compartment, near the evaporator inlet tube. Each of the service ports has a threaded plastic protective cap installed over it from the factory. After servicing the refrigerant system, always reinstall both of the service port caps.

Low Pressure Service Port

Thanks for the reply, but my 2003 Sahara does not have a service port located on the largest diameter alum. line. Are you sure the 2003 is supposed to have one ??

Look directly in front of your underhood fuse block between the airbox and fender, that's your low side connector.

The picture Rubi posted is sort of "Generic TJ" in 2003 they changed the location but never changed the pictures in the manuals. You'll find that a lot on 2003 and later information.
