Hey guys, I am new to this site and own a 73 L48 four speed coupe. The windshield wipers will not shut off. I am told it is the wiper switch in the dash at the top in the center? If so, seems like an easy fix. For now, I unplugged the motor at the firewall. Also, my oil pressure gauge is broken, have a temporary one under the hood, it shows pressure. Bad gauge? Thanks.
