Hey all,

I was out last night driving my evo and I came to a kerbside stop to park my car. I usually wait 30s-1min before I turn the engine off for the turbo to cool down. All I remember was turning the A/C on and then turning the car off after 3 seconds of it being on.

Later in the night, I turned my car on and started driving. It got a little warm so I turned on my A/C and nothing happened; fans work but no cold air. I toggled all the settings by changing it to the coldest temp, turning the fan to full blast, pressing down the A/C button on/off (the light comes on btw) but all I got was a blast of warm air.

I did some snooping around today to get the problem fixed by myself. Mind you, I've only owned an evo for a month now. I can confirm that when I turn the A/C on, there is no engagement of the A/C compressor.

I removed the plastic cover under my steering wheel to get to the fuse box (why have they made it so inconvenient for accessibility?) and used my voltmeter to run a test on all the fuses (on both pins).

I found this diagram on another thread in these forums:
(source: here)

All the fuses worked except for #6 in the pic (not sure what that one's for). I suspect the 30A fuse (#19) is the A/C one and I can confirm that worked. Just to make sure, I resat the fuse.

I also tried to look for the relay for the A/C. I've looked up in these forums but I couldn't find the help I needed. I popped the bonnet open, opened the relay box and found this:



Why is there no A/C relay? or am I looking in the wrong place? The A/C has worked perfectly fine in the past and my car's done <50,000 kms.

Also, I'm not sure if the following shot of the A/C compressor would help:


I think that's the compressor with the black wire sitting on top of it. The unit directly above it is the power steering motor (right?).

Would appreciate any help and guidance I can get to fix this issue.

Thanks

 

This is a common problem with the Evos.

1st, your AC relay is there. it's the lowest in your picture.

The compressor clutch wears away. There is a HUGE thread on here about how to shim the compressor clutch. It can be done with the AC compressor in the car with basic hand tools.

Do a search for "AC not working" or "clutch not engaging" and I am sure you will find it.

 

Thanks for your reply

Will look into it. I'm just shocked that it can go from working all fine to just dead :/ Thanks for referring me on. There was a bit inside me that was doubtful of anything more serious than just a relay issue.

That's how they fail... on or off. no inbetween.

 

You dont need AC...lol

 

I live in Sydney. Just last week we had a day with a 44 degree max (111 Fahrenheit). I'm sure an AC would be nice if you don't want to sweat into your immaculate Recaros haha

 

If low on freon a/c compressor will not turn on. Check to make sure no leaks and freon is full. If all is good then it the clutch on the compressor

 

Evos don't use Freon.... at least they haven't for nearly 20 years.
