Hi All. Looking to tap your expertise please. I have a 2017 LWB Shogun SG3 and apart from modifying the rear lights, havnt really touched it as it was bought new and all systems seem to be ok. I left it sitting for 4 months whilst I was away on a long holiday and the air con is not working, The air con is not blowing cold (compressor clutch not kicking in) and all indications seem to be that the gas level is low. From what I can gather this situation will prevent the compressor clutch from engaging. All tables and sites I have looked at suggest the air con gas is R134A and certainly the L port (located just below the fuel filter) looks like a R134A post as pictured on some previous posts.

I know sub zero will give me a row here for trying to do it myself but I bought an STP recharge hose and R134a gas from halfords but cant get the nozzle from the recharge hose to lock properly on to the L port. Unfortunately I have unwrapped the seal on the gas cannister so cant take it back.

Any ideas anyone what Im doing wrong or where can I get a quality recharge hose?

Thanks. Tui

Hello community. Time to fess up re my previous post. Looks like I made a major error.
Despite several Air con websites i consulted to find out what air con refrigerant my 2017 shogun used, all of which told me R134a, I was wrong.
No wonder I had a hard time trying to connect the R134a adaptor.

Apparently all cars made after 2017 use the newer more expensive (and more environmentally friendly) R1234YF, but as my Shogun LWB was registered in 2017 (but probably made in 2015) I believed it to be the old style, as confirmed by several manufacturers.

My 2017 LWB Shogun SG3 actualy uses R1234YF. It says so on a fairly obvious sticker on the bonnet landing panel.

Sorry if I have put anyone to any trouble.

I am afraid that I just don't understand why people buy those DIY things from Halfords.

All you can do is top up the gas - what about leak testing and the adding of lubricant?

I don't actually think I have ever known anyone who has managed to do a successful job with them.

I always use a specialist and I don't think they are that much more expensive than trying to get a good job from a DIY cannister.

Thank you where what.
Turns out I had a major leak in the pipes that run towards the rear of the car. Put it in to mitsubishi to have it sorted under warranty and they fixed the problem and 're gassed the system.

Lesson learned.
