What is this part? The silver item on the left with a number 1 on it. On a 72 CS with a/c, pwr. windows, rear window defogger. It isn't in my chassis manual that I can find. Note the large wire going to the horn relay jct. block. Looking to find the door buzzer items to repair that. It isn't the blower motor relay I know that much.

 

thats the relay for the electric rear window defroster, Tim

 

The rear window defogger relay is shown in the 1972 CSM on pages 15-26 and 15-27.

The key buzzer is part of the horn relay. The switch is built into the steering column. This is shown in the CSM on page 12-75.
