| My air con is not working at all, push button light comes on and nothing, engine idle does not change at all.Does this mean i need a re gassing or is it stuffed, the rad was replaced before i bought the car so i dont know if that is a factor. Its starting to get hot over here and i would really appreciate any help |

| It sounds like the gas has leaked out, but have someone find and fix the leak or regassing is only a temporary fix. One common leak, is an O-ring at the front. Shine a torch in through the front grille and if things look a bit oily on the passengers side, it is the O-ring leaking. It is a simple and easy (low cost) fix. |

| it could be out of gas but you'll need someone with all the gear to check it first, well thats the law but you could just look around all the pipes and compressor(should be called a pump cause nothing gets compressed) for oil and even the condenser some times you might find something. Just keep in mind that the people that do air cons should always check it over for all the leaks before they can re-gas, its a law. air con quotes can get a bit steep, tho will normally have a warranty to that shop if it doesn't work. oh! just remembered if you can see any stickers in the engine bay about uv dye then wait till night and get a black light. just keep in mind that you'll have to see an auto electrician or air con place to fix it and re-gas, and they'll check it all over anyway(or should) by law. |

| Even if you have no freon (gas) in the system, the compresser should still come on pulling a draw on the engine. Leo Croker wrote on Friday, June 08, 2007 - 09:48 pm: engine idle does not change at all
You may need more than regassing. |

| If the gas pressure drops, the compressor won't switch on. Toyota smarts. |

| as peter said compressor wont turn on without any head pressure. and its never just needs to be regassed, it'll have a leak. take it to an aircon place and get a quote which wont cost much, then deppening on what it'll cost to fix is your choice to pay or not really. |

Really?? I had a slow leak about 3 years ago, and when I turned on the a/c it blew hot air, but the compressor still kicked in putting a drain on the engine. I had to eventually replace the whole system for $1600 USD!! |

| There is a pressure sensor that should have stopped it, saves damage - unless they left it off the SC-300? |

Or mine was broken, maybe thats why they recommended replacing the whole unit. |

| Sorry to dredge up an old post, but thought it better than starting a new thread. My AC just stopped working, worked on the way to work this morning and when i went to come home it wont turn on. Lights in the display turn on but none of the buttons will work, not even fan or demisters. Im thinking (hoping) its just a fuse? is there a fuse that controls all of the buttons on the panel? Aircon has always been nice and cold, climate control works fine for the last 5 years, so im hoping its not a leak, whadaya rekon aircon gurus? |

| Anything flashing on the panel? There is a page about AC diagnostics on here somewhere- try the first or second section down. |

| Try just turning the ignition switch to ON in the above diagnostics ;) There is a fuse in the foot well for the AC computer btw. If you have no display or switch functions you may just have a loose connector at the back/glove bow. |

| Yeah i tried that Luke and no deal, no lights nothing. Yeah i am more convinced that it is just a fuse / loose connection but just havent had the time to pull apart the console to check it out |

| Well I have checked the fuses in the drivers footwell, all are fine. All plugs were in nice and snug. Still no power or lights to climate control though. I have taken out the whole climate control unit, is there any way i can test if it is working? I can't find a plug wiring diagram anywhere so I can just hook it up directly to 12v. |

| Can anyone explain what the strange smell that i'm getting inside the car might be, (no its not me!!) have an idea it may be something to do with the air con, does this mean i have a leak? |

| Might be something nasty in your air inlet? Does it happen when the air flow is set to recirc? |

| Peter, I dont think its something nasty in the intake, i'm sure I've experienced it before from a portable home air conditioner. My main concern is that if it is a leak with the a/c, is it dangerous to breath in? |
