Mitsubishi Repair: Issue with ac system, mitsubishi mirage, coolant level

Question
To start, I have a 97 mitsubishi mirage ls coupe sport, manual tranny.  Bought the thing about a month and a half ago.  Car is in great condition, but every once in a rare while (maybe once every one or two weeks), I have a problem with the ac not working.  Most the time, it blows like ice cubes.  However, in these instances, it just doesn't work at all.  

Checked the coolant level and it's fine.  The times it seems to not work is when it's extremely hot out (95+f out), and it also seems to happen after the car has been driven, warmed up, then shut off to go in a store, etc., then restarted again while it's still warm.  if when i have this problem i shut the car off for an hour or two and try the ac again, it works fine.  

Under these conditions, it seems to me like something electrical, or that maybe the compressor clutch is getting stuck when it's getting too hot.  To be honest though, never worked on an ac system before, and not even sure how to check and see when the compressor clutch is kicking in and out, cause when I had the wife turning the cars ac on and off and i was watching it, i didn't notice a bit of difference.  

Any feedback you could give me would be greatly appreciated.  If you're not sure of what the problem could be, if you could even just point me in the direction of someone that might be able to I'd greatly appreciate it.  
Thanks,

Answer
AC,
There's a good chance it's an eletrical problem based on your description.  When outside temperatures get as high as you indicated, eletrical components can perform extremely poor because as temperatures increase, the resistance in these components also increases dramatically.  So, if an eletrical component is worn, the high heat can prevent it from working at all.  This could be anything from one of your A/C relays to a temperature sensor.

When the A/C gets turned on, you should notice a clicking noise and both your radiator and A/C fans may turn on.  The engine should also start to idle slower for a second and then return to normal.  If you're not noticing any of these things, you should definitely have a mechanic who is familiar with A/C systems to examine your car.  You can call around to your local garages and ask if they service A/C systems.  Many do, and should be able to help you.  Just be sure you bring them your car when you know the problem will happen, which may be the toughest part.
Good luck!
