Air con advice

[Deb24]

Auto Electricians out there that could offer some advice?

Hi. Bit of a long story ... But my air con in my car won't work. Summers coming and I'd really like it sorted. About a year ago I took it to an auto electrician. He filled the air con gas up, then checked it over. When I returned I was told that it was dangerous and could have caught fire so they disconnected the air con and to fix the problem was $700-$800. 6 months later I returned to get it fixed. Came back later that day and was told they reconnected it and there was nothing wrong with it and it works fine! Confused but happy I had extra cash for school uniforms. Anyway air con never worked since. It turns on then after 5 seconds it turns itself off and the air con light flashes and blows hot air! I'm reluctant to go back again as I don't have the money and I'm a bit over it. Any ideas in what it might be? Simple fix? Thanks appreciate your advice. Sorry about the long winded post

Sounds like the 'catch fire' story was just a ruse to part you of your cash.

You may have a small leak of the refrigerant in the system. Any decent auto shop should be able to pressure test the a/c unit and advise you from there.

Steer clear of that original auto electrician. He must be walking round with solid gold spurs on his boots by now lol.
