I thought I had a problem with the A/C controller in mine as well. Turned
out to be a loose connection. The nice 21-pin spade connector (very firm)
apparently runs to a TERMINAL BLOCK at the side of the console. This is not
visible until you remove the carpeting on the side of the console. A few of
the screws were loose, and the ground wire had completely come off. Didn't
check the wiring carefully until the formerly intermittent unit stopped
Probably came loose over the years. But I still wonder why have such a
wonderful connector at the unit and then run the wiring through a terminal
block. For easy troubleshooting by the techs?
Your a/c system is a closed loop. If you have lost coolant, there is a leak
and adding more coolant will not correct this problem. Go to a shop who
knows what they are doing and ask if they have fluorescein dye injection
which is put in the loop. Under special light, the leak becomes obvious.
Then you will KNOW what the problem is and what needs to be replaced instead
of guessing. P.

Once there is a problem it is easy for it to spread to other items in
the system (this means added cost!). Get it looked at by an air-con
specialist. Ask for a re-gas, they will pressure test it as part of
the re-gas and let you know if there's a leak.
There is a pressure sensor in the system that will shut it down if the
pressure is too low (leaky refrigerant). It sounds like you are on the
threshold of that. On/off cycling. A/C gets a pounding, the system on
your car is no better or worse than most. It is just that people think
A/C is a fit-it-and-forget-it item. It isn't. It needs regular
maintenance to stay working properly. You should also run it once a
week (even in the winter) for a short burst at least.
