Hi there,

The A/C compressor relay should be in the underhood fusebox.

Have you checked the systerm pressures, and verified the system gas is correct?


Customer: replied 10 months ago.
The system has gas, the underhood fusebox does not have an a/c relay.
The ac fuse under the steering column has already been replaced.
Customer: replied 10 months ago.
I just need to know the a/c relay location, it must be behind the dash somewhere?
Expert:  Gary replied 10 months ago.

Hi again,

Does it have right amount of gas, or are you guessing?

Does the compressor wire go live with a test lamp, when turned on from the cabin switch?

I have a feeling the relay is an onboard relay within the fuesbox.

Can you post a pic of the fusebox covers?


Customer: replied 10 months ago.
The black cover is the underhood, grey is under the steering column.

Ok, can you locate the horn relay for me?

The A/C relay will in there.

Have you verfied there is 12v at the compressor wire with the A/C on?


Customer: replied 10 months ago.
The horn fuse (10) in the underhood black fuse box is ok.
The only other fuse/relay box i found is the one attached.
Customer: replied 10 months ago.
I also just checked inside each kick panel and could not find any other fuses or relays

I don't think I can help you any further, since you are supplying some good photos,

but you haven't answered my question of where the horn RELAY is.

If you find the RELAY, then we can continue.

I will opt out now, another tech may be able to help you.

Hello and welcome to just answer. My name is ***** ***** here to help you. I can't ess or hear your vehicle so I rely on your input to my questions so I can help you better. I read your problem and understand you need to locate the A/C relay. I also understand you said it has Freon in it? what is the meter reading because this circuit is pressure sensitive the A/crelay should be behind the kick panell under dash. because your in australlia I'm not sure if it's the right or left one . After you locate it you then can jump it to see if the clutch engages, if not it could be a faulty clutch or wiring to it.If it does engage it could be low pressure or the pressure switch on the line which you can jump too. Hope this helps you better and if you require further help I'll be happy to do so..
