    Fuse blowing

    Hi to all, I purchased a 87 bmw e30 convertable with a hardtop. When I turn on the ignition fuse # 8 (rear window defogger/defroster) blows. Before I go through the whole trouble shooting process has anyone a idea what would cause that? I know its a direct short but maybe someone has a idea what to check first, thanks.

    I'd start by pulling the relay and testing it.
