Aircon Problem

[Anakha]

Hey guys my aircon and climate control is only blowing out hot air. a/c on or off... even the fan on or off... all it does is blow out hot engine air. What do I do???

try turning it on, make sure its set to the coldest and hit the recirculate button and then turn it back off, that should stop the hot air coming in. you could also do the a/c diagnostic and see what error codes pop up. there is a tutorial in the tut/diy section.

Sorry I think I used the wrong word. Its the old school analog aircon - with the levers. I can't do a diagnostic. And I tried what you said with no success

hi buddy you will probably find that your system is very low on a/c gas or have none at all this will stop unit from coming on as there is a low pressure switch in the system to stop the compressor turning on and siezing up through no gas or low gas level and no oil circulating since oil is carried by the gas in an a/c system need to get gas levels checked first by an expert and then go from there let me know how you get on .......By the way was in automotive airconditioning for 5 years so i have nt missed much ... let me know...........................

Its hard for the fastners to slip on the mechanical control arms. I would say your gas system has developed a leak. Take it to aircon shop and get them to pressurise the system with coloured die to show u leak

also check aircon fuses

Sorry guys, I kinda havn't had computer access for a few days. Onto the situation at hand -

Before taking it into the shop I decided to have a play with the system, just your basic schoolboy 'lets play with knobs and see what happens'. After a little while I ended up making the system fix itself. Now all it does is blow cold air on full.

I'm assuming now that is it actually the control arms... anyone to second that opinion? And how do I fix it???

Pull off your entire dash, you should see some rods somewhere down the side of the AC and a little link that fastens to it. Tighten that

Or its your blend servo motor, do a search in the forums for it but you'll have to also dismantle the dash
