Climate Control Panel (ECC) question...

If the lights flash when the car is first started it's because the system has found a fault. It doesn't necessarily mean you need to add freon. If you have a 93-95 you should have a diagnostic panel under the hood over by the fill neck for the windshield washer bottle. The first thing to do is read the codes since this will tell you what the system is seeing as a problem.
I don't know if the system knows to set a code for low freon but if you look at the list of codes it could be anything from the temperature sensors with the little fan that is built into the grab handle above the driver or passenger seats or one of the blend doors not responding properly to its signal or one of the temperature sensors in the ducting that has failed. I have a couple of these codes.
Not sure if this is a complete list.

Yes, there are plenty of them. You can use any search engine (Bing, Yahoo, Google ...) to get a description. Just type in the trouble code. Once you've done that and it says .... , then you use some of that language or the parts name to search some more. You might also be able to search this forum (volvoforums), Volvospeed, volvoforum, turbobricks ... for a thread on any of the trouble codes.
It's likely you don't have a brand new code no one has ever had before so there should be threads that apply.
You could also post them and have someone here point you in the right direction. I like to give people the tools to find out and I think most of the folks here respect someone who's at least made an effort to find information.
