166 Lusso heated seats

Hi all, me again. Forgotten how many little problems you can get with an older Alfa!. Anyway, the heated seats don't seem to work. The switches are completely knackered. One has a burnt connection, the other makes no coontact and a third (spare?) I found in the glovebox also doesn't seem to stay down, although it does make continuity when depressed. I am happy to try to get new switches, but was wondering if anyone know how to test the seat heaters before I waste money on redundant switches. HAving dismantled the broken switch, it appears that he 2 outside connections link across to provide continuity to the heater, the middle 2 contacts being +ve & -ve for the LED. If I just bridge across the two outer contacts should that 'heat the seats', or are there other components in the electrical chain (I have'nt got wiring diagrams yet...have sent off to e-bay for workshop manual on CD!). If I do bridge across and the seats still don't heat what else can I check. Any info welcome
