Pair of pliers and pull on the relay. That's what I did with mine

Thanks, does it sound like its worth buying a relay to try myself or is it likely something else and need to leave in to garage?

 

when I first bought my car, the AC wasn't working. took it back and they re-gassed it, still not working. so they then changed the relay and hey presto... nice cold air.

that was years ago, but last week same thing happened. after a few months not using the AC, I flipped it on and I was just getting air the same temp as outside.

I thought, hmmm perhaps getting a new relay again would be a cheap fix instead of taking it to a garage... so I bought the new Mitsuba one.... but that didn't fix it either.

needed to get a garage to look at it in the end, they re-gassed it and charged me for the pleasure... so now I have 2 x relays here, both working fine lol

 

Im not that bothered about it tbh, it worked well last year when I was setting to low. Since then it's been left around 20 auto but getting a few days now where it would be nice to have again.

Don't suppose you want to sell a mitsuba one cheap?

 

A relay brand new will cost around 20ish quid. Worth a punt IMO, if you can get one on the cheap then go for it. You don't need a garage to change a relay lol.

 

:dito:

 

Yea not expensive but I'd still rather not buy one if I don't need to. Wouldn't leave in to garage to change a relay, I'm slightly more competent than that lol. Just wanted to make sure there were no clips or anything holding it in before I try and yank it out.

Ordered a set of mats at the dealer earlier, so when I pick them up I'll ask if they have any I can try.

 

You can pick up a Denso one on eBay for £17. Toyota/Lexus use a fair bit of Denso so much be a quality brand

 

no probs mate.

Got a relay from Honda and an independent place tried to gas it but compressor still not kicking.

The independent place want the car on Monday to look at it better but I'm not sure I trust them to do much more. They seem a bit rough, just let the gas out of low side and then tried filling it. I thought they should have been checking pressures and stuff on both side before doing anything.

Is there anything I can try looking at myself or should I just go to Honda?

 

Was the indi a general garage with an A/C recommendation or A/C specialist?

Did they allocate you a slot to investigate or just take a quick look and ask you back for a further look-see?

Yes their kit should have first performed a low pressure EVAC test to check for leaks. Then pressurize the system, without doing this either the low or high pressure switches might not allow the compressor to kick-in.

If relay didn't help then someone needs to check if the compressor is kicking in, can you hear the relay click when the A/C is set on?

There's a few 'How To's floating around on what can be checked and options you have.

Good luck getting it sorted.

 

They are radiator and air con guys not general mechanic. They asked me to come in at 3 today where he released the gas straight away and then tried to top it before I went and got a relay.

Never mentioned any pressure switches just said they would need to check where and what was getting power. Said to leave it in on Monday morning.

Spoke to dealer and they wanted 75 for an hours diagnostic but their mechanic said the other guys were pretty clued up on the air con stuff so I'll just let them look at it.

I'm not even that bothered about AC but don't like thinking that something's broke on the car.

Will they need to take much off the car to look at it? I'm worried they'll scrape the bumper or something if it has to come off.

 

Without a FMIC up front they should be able to check the condensor/drier by only removing the slam panel and possibly the under tray.

The front bumper should be able to stay put. However if they need to swap out the condensor/drier then the bumper may have to come out if they struggle with the lower hose fixing.

Now you have a relay, have you tried it?

 

Yep I went back down to them and he connected up the gas and put the relay in but no joy.

Read on one of the threads about disconnecting battery so trying that now.

 

Been told the clutch is seized in the pump, take it he talking about the compressor?

Anyone any ideas where to go from here? I'd like it fixed but not wanting to spend £100's for A/C

 

Here? http://www.civinfo.com/forum/how/108072-ac-condenser-overhaul-shim-replacement.html

 

Mine doesn't work at all, that thread seems to suggest shims as a fix for intermittent A/C.

Might be worth a shot anyway, I'll have to get round and see them he said he has pics of it.

 

Dismantle the clutch and pulley assembly to find out what the problem is.

It could be a simple shim or a burn out clutch, both can be sourced separately.

Then you won't need a re-gas and repairing the duff item should be cheaper than a new compressor.

#9 the clutch is 1/8th the price of a complete compressor.

 

Guess I'll be sweating out it 3 days a year at that price lol.

Let me know how it goes, I'd like to get it fixed for under 300.

 

no probs i'll update you when i know..

 

Hi when u look down from the alternator u see the compressor, if the outer ring is not turning the compressor is not engaged, to test this take a feed direct from the battery pos terminal to the clutch which is adjacent to the alternator.if u are not sure use a fused jump lead. There are two fans under the bonnet, left one is AC right one is engine cooling. AC fan will start when u switch AC on, which u hear from the cab.

 

The pulley is turning but the clutch plate isnt. I've been out and without even having the key in tried to turn the clutch plate but its rock solid, should it be?

The A/C fan starts as soon as I turn the A/C on in the car and I can hear the new relay click.

Been going through the troubleshooting from the workshop manual. Next step it says is check clearance (as suggested) and field coil as I'm not getting a click when I put the jumper between 1 and 2 in the relay socket.

 

Can someone with working A/C see if they can move the clutch plate without the car running please or anyone in the know confirm if it should move?

I'm stuck between replacing coil/clutch and replacing compressor.

Haven't had a chance to get under to check the gap and coil resistance, chucking it down and me worried about A/C :facepalm:

 

Hi sounds like u have a sized compressor, normally u can reach down and turn thcompressor outer plate.stil may be worth jumping from battery pos terminal direct to clutch feed which is just above alternator body, try this with engine at rest and ignition off.alternatively if u have a multi meter measure the clutch do resistance which I think is approx 7ohms. But my main concern is the sized clutch plate!!

 

Thanks, it would not budge at all. Too much stuff to pay and other more exciting things to buy for the car (coilovers, carbon bonnet, flashpro etc etc... lol).

I think I'll leave this til next summer, that way I can put some money aside until then to soften the blow of a new compressor. I will measure the resistance of the coil some day out of interest.

thanks all for your responses.
