'92 960 problems

I have a '92 960 sedan. nice car. I also have the infamas tranny problems and also the climate control sometimes blows cold and then suddenly the compressor kicks off and might be off briefly or a few days and then it just kicks back on. i have the right coolant pressure in the system. any ideas?

Check your fan relay , Make sure it comes on --MIKE

Change the transmission fluid a couple times a year.
