My Car is Making a “Clanky” noise

Try having your kid put a dime in you cigarette lighter socket and see what happens to your electronics. Can you imagine how hard it was to diagnose that one. Didn't completely short the system and really screwed with the electronic speed-o-meter and dash functions. Brand new mopar too.

We had a gal with a Electra 225 back in the day and one of the kids put a penny in the rear door light socket. Same deal as yours, it would blow the accessory fuse and we couldn't get it to act up. We put a circuit breaker in place of the fuse and it would reset itself. We finally found it when we had to get in the door because the power window quit working. Pull the panel and out pops the penny.
