Question ac not working need help before it gets too hot

Hi all, I'm new to the focus world so please cut me some slack if my questions seem simple.

I recently bought a white 02 lx sedan with an automatic for $600. It has just over 146000 miles but is on its second engine, so about 70,000 on the second, I guess the first engine blew itself up for whatever reason and ford replaced it under warranty. It seems to run great now that I've given it a decent tune up, still have a few things I need to do before its perfect.

Anyway the ac doesn't work, at all. I knew this when I bought the car. Basically nothing comes on. When I turn the fan switch to any one of the settings nothing happens, the blower motor doesn't turn on. Also when I press the ac button it doesn't light up, my guess would be because the system isn't on.

The previous onwers informed me that the ac did work last summer but not on all the fan settings. I'm thinking one of 2 thins happened, either the switch itself went completely bad or the relay/fuse is blown.

Anybody run into a simillar situation? If so how did you fix it? Or any ideas on what the problem could be? Also if it is the switch on the dash does anybody know about how much one of those costs?

Any help would be great

Thanks

First you need to check for Freon in the system, and see if there's any sign of leakage. No freon and the system won't cool.

But the internal cabin fan should work on all speeds. Sometimes the fan resistor pack fails.....but the fan should still work on #4 speed. Sometimes the switch fails.....than a single speed might not work but the others will.

If nothing works, you may have blown a fuse or you have a bad relay somewhere. Lots of things can be wrong.....

Oh.....you won't make friends here if you post the same question in multiple threads at the same time.

Actually... I would check the switch first. The AC light will not come on if the fan switch is on 0. Your fan does not come on when you rotate the switch between 1, 2, 3, 4, if I read your post correctly. That tells me that your switch always thinks 0 is selected, and it won't kick the AC compressor on.
