Aircon seems to be bust.

[ZedHead]

Quick question to all those in the know.

 

Does it stand to reason that if your revs don't change with A/C on or off the compressor is shot or will the compressor not work if the system needs regassed?

 

Really hoping I don't have to shell out for a compressor.

 

Alex (Zmanalex) you might need to have one on standby.

 

Cheers Guys

I don't think my revs changed at all with aircon on or off.

 

Does it get cold when you put it on cold? If not then its bust

 

...... also do you get a puddle under the car when you park after having the aircon on?

Revs didnt change for me when i turned the air con on.

[Ekona]

Check your belt. I suspect it's missing.

 

 

Same thing happened to me on my old car.

Engine will usually tickover at slightly higher revs with the air-con on.

 

May just need a re-gas/topping up - a whole lot cheaper than a new compressor

[ZedHead]

Belt definitely there as far as I can see. It's the belt right under the air intake isn't it?

 

Hard to see if there isn't a puddle under the car at this time of year in the Hebrides. Maybe I'll run it in the garage for a while (don't worry, with garage door open)

Revs don't seem to drop on The Zed. From my limited experience of A/C then the bigger the engine the less the revs drop.

David,

 

Zmanalex on standby with plenty of air con. compressors in stock if required mate

 

The revs will drop slightly when you switch on the air con.

 

There are two belts on the front of the engine, the shorter inner one is for the air con.

 

If all looks good and you are not getting the air con to work then I would try a recharge first.

 

If it does not hold pressure then get the garage to run a dye through the system to determine where the leak is.

 

I will have all parts in stock to fix this for you if required including air con hard lines.

As ever Alex,

 

It's nice to know you are there to dig me out of the poo again

[rmgthatsme]

Just a thought but could it be a faulty on/off switch? Second suggestion is that if it's very cold where you are, have you turned the climate control dial to a low enough setting to actually activate the compressor? Sometimes can be the simple things that fail...

Hope this helps

Also might be worth checking that the ac clutch plate is still intact.( its a plate that bolts onto the front of the compressor) Mine fell off on the way back from the jock land hoon, found it on the under tray 500 miles after it came off

[M13KYF]

revs go slightly up on tickover when switching on the aircon

[ZedHead]

Thanks guys,

 

I shall check all the possiblities out.

 

Can anyone recommend a good do it yourself regassing system as my local garage in the Hebrides can't do it apparently?

 

cheers

Don't bother DIY the gassing yourself buddy. It's just not worth it. A refill kit costs the same as getting it done at halfords. Their machine will also tell you before it re-gasses whether there are any leaks. If so, get these rectified. Other points to note:

 

1) If you don't have any gas in the compressor, the aircon unit will NOT come on.

 

2) Check the belt is still there and has not come off or shredded.

 

3) The engine note should sound different as soon as you switch your aircon on as a test. The louder your exhaust, the more noticeable the sound.

 

If all the above checks out then Alex is your man for a replacement unit.

 

Hope this helps.
