I just bought a 90 Mark VII LSC and it has a couple problems. 1st there was elec noise in rear speaker so I unplugged it. Couple weeks later & it is now the same in drivers door speaker. Today the trunk closer stopped working. I replaced all but the 4 amp fuses plus 2 20amp circuit breakers. The ceiling display doesnt work, the cruise control stopped working (previous owner said heard a pop sound that may have been a fuse) and the ignition switch stuck the other day & wouldnt turn.
