Switch your power window circuit on command with the Standard Ignition RY-500 Power Window Relay, a 1992-1994 Porsche 911 relay that is also a direct-fit replacement for the 1991 Porsche 944 and the 1992-1995 Porsche 968. On the 911 it is listed for 1984 and for 1992-1994. See the Buyer's Guide tab for the full application details.
A relay is an electrically operated switch. A small control current energizes the relay, which closes its contacts and passes the higher current the power window circuit needs. If a failed relay is why your windows won't move, work only now and then, or you hear a click with no window movement, this part replaces it. Diagnose the circuit first, because switches, window motors, wiring and fuses can cause the same signs.
