I have a ‘65 Thunderbird convertible with a puzzling ignition switch issue. Periodically, the car will not turn off using the ignition switch. I have replaced the complete switch assembly twice (new replacement unit from Larry’s Thunderbird) and it will work fine for a while and acts up again.
Are there any other potential causes for this issue - aside from the ignition switch?
Thanks in advance for any help!
