How do you check for bad relays on a 1999 Cadillac deville?

Answer 1

To check for bad relays on a 1999 Cadillac DeVille, first locate the relay box, typically found under the hood or in the passenger compartment. Inspect the relays visually for any signs of damage, corrosion, or overheating. You can test the relays by swapping them with a known good relay of the same type or using a multimeter to check for continuity. If the relay fails these tests, it likely needs replacement.
