Don't you dare work on your own car...

Unread post by Wombat1965 » December 2nd, 2010, 5:05 pm

Just been cruising the net trying to problem solve an annoying fault with our Land Cruiser air con system...clutch on the compressor not cutting out (even when you switch the air con "off" at the dash switch...but it does cut out if you pull the wire on the compressor)...appears to be most likely the magnetic clutch relay...which very cleverly is listed as a "non replaceable unit" intergral under the fuse box under the bonnet...the entire fuse box has to be replaced to fix what should be just another $5 relay... :crazy:

Anyway, on US and English four wheel drive sites, I came across home regas kits for your air conditioning...usually two cans of R134 gas with a fitting and hose, also containing UV dye and a UV torch to look for leaks.
The price? Around $40 to $50 US...

Why are people overseas allowed to do this sort of work to thier own damn cars, and yet here, you have to take your car to a licenced air conditioning specialists to get it done, and it's illegal to vent old air con gas to the atmosphere?

I wonder how many air con shops would go out of business from lack of thier major business (simple regas's) if you could just walk in and buy these kits here?

They're not allowed to do it. You've pretty much answered your own question. It's illegal to vent gas to atmosphere hence a license is required to handle it.

By the way those cans are available here. However I believe you need a license to purchase them.

The specialist will never go out of business because when the DIY idiot f#*ks things up he needs somewhere to take his vehicle to get fixed properly. :D :D

could you imagine if every Joe blow could just top us his A\C with gas.
1st problem would be they over gas it and damage the system
2nd problems they misdiagnose everything with being low on gas.
3rd problem- specialists would have to charge through the roof to stay in business making unviable to get them to fox anything.
Theres alot more to AC systems then just gas and alot people dont understand that
some people dont even know the difference between there fan and the AC. They think its the one thing.

Same as old "mantlepiece" arguments that was used to import non .au approved modems. You were allowed to import/buy them because it didn't mean you were actualy going to plug them in to the phone network. You loved the design so were going to put it on the mantlepiece to admire.

Hah, like certain knives and lock-picks.

You can buy them, just don't get caught carrying/using them.

there's this thing called an Ozone layer.
It's got a hole in it.
A/C gas helps make it bigger.
this is not a good thing

None ... they'd just be doing repairs to peoples' stuff-ups rather than re-gas ... ...

Don't need a license to buy R134A - You can buy it in a small can at Jaycar. Although I think it had an "ozone safe" label on it. Weird.

You can buy the regas/repair cans here I was looking at one a few weeks ago to fix mine then I thought it would cost the same to get someone else to do it and if it stuffed up I would have a warranty to fall back on. So I got a shop to regas it for me then he couldn't find out why it wouldn't work so after 6 hrs of being there I walked in to find out if it had been finished, and told it has pressure but doesn't work. I brought it home at a discounted rate to find a broken wire, I returned the next day and offered to pay the outstanding balance but he said I found the problem and fixed it myself so he wasn't going to charge me for that.
Last night I lay in bed looking up at the stars in the sky and I thought to myself, where the heck is the tent gone.

Unless the air con specialists that I have spoken to are lieing to me, the other reason why you shouldn't regas your own cars air con is the gas that goes in is highly toxic as well as unsafe for the environment, you should never breath it in when degasing your system.

They actually warn you all over the workshop manual about keeping away from venting gas...the main reason being that A: it's a refrigerant and just like any other escaping compressed gas (LP, etc), can freeze skin, and B:, you can't breath it anyway and might pass out at high enough levels, toxic or not.

I agree with the statement about "taking it back twice"...I've been to many shops over the years with various cars, and unless something obvious is apparent, their first line of attack is to regas. Then if it leaks out again over the next couple of weeks, they look further. A home kit to do a simple regas, especially one costing only $50 or so, would be a huge boon for home mechanics. Then you've only wasted $40 or $50 before finding out it really needs serious work, instead of $170+ for a simple regas with no extra parts at a shop...

Gentlemen,
Bears do not have this problem, as we use the 60 x 180 Air Con (60kph and the windows open). Sorry but I do not have or use Air Con, as I always drive with the windows down. There was no such thing when I started to drive. Also I like to hear what is going on with the vehicle etc. Although this practice has cost me 41% of my hearing, but in some cases thisloss is a positive. It can get a little wet sometimes, but the furry suit dries out :) .
