does this car use a fuse box, or what is used?
Ive never had a 38 Cadillac but If its anything like my cars it just has the heat sensitive contact strip atop the light switch.
There is no fuse block on these cars. There is a circuit breaker on the light switch. If the car has a radio, there is a feed for it in the dash harness, and the radio feed would have in inline fuseholder in it. The heater may have a fuse holder in its feed, but I don't recall seeing one on my car.The dash harness is the same for the 38-50, 60, and the 60S. I think that the above is all of the circuit protection in the car.
