It was fuse number 16, right? The fuse and fuse holder are simply overloaded in the basic design. There is too much current draw on the fuse holder. It was fine when new, but too many heating cycles weaken the grip of the fuse holder on the fuse after 15 years. This is a very common problem on 700 series Volvos. You have two choices:
1. Replace the fuse block with a new, or good used unit.
2. Buy a new fuse holder and power the AC and heater with it.
If you choose option 2, you must pull the central electrical unit out and turn it over. Splice a fuse holder into the lead supplying power to fuse 16. Splice the load side of the new fuse into the black lead supplying power to the heater and AC unit. You must continue to supply power to fuse 16, as fuses 14 and 15 are fed from the supply side of fuse 16. That is the repair I made to my wife's 86 745T. The black wire with it's connection inside the plastic socket on the underside of fuse 16 is the supply wire.
