Engine Size: 1.5
Hi Guys. I'm not an air con bloke but, with instructions can do most things. I'd just like to know whether this is something that I can do or whether I have to take it to somebody. The AC turns on and off within about 90 seconds and keeps cycling like this. The air definitely starts to cool, and once it reaches "cold" (it's not that cold but certainly colder than room temp) it shuts off again. Takes a very long time to cool down a hot car this way. Long drives will see the cabin reach a decent temperature if it's not a scorching day. My logic tells me there's an issue with a thermostat somewhere, but I don't even know if that's how these operate. Any advice would be great.
Have the freon charge recovered and recharge with the proper amount. This will eliminate low charge as a possible problem.
Could also be overcharged if someone has worked on it.
Check that the condenser fans work. Non-working fans will cause trouble with the car sitting still but it will work normal at highway speed.

OK, movement doesn't have any effect on it, regardless of speed. I had somebody out a while ago doing another car and just asked him to check the level, he hooked up a few pipes with some valves and said it was fine. Can you tell from the pressure like that or do you need to empty and refill to accurately determine that?
Pressures can be an indication of charge level. But the only way to know for sure is to recover then charge by weight.
I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!
