Checking / replacing relays

Recommended Posts

Is it necessary to disconnect the battery s to pull out, check, or replace a relay in the circuit box?

          No,  pulling them with the batteries connected and the key in the off position will not hurt anything.

Easy way to test relays is take a known good relay like the horn which is a smaller relay and swap it with what is questionable if the problem goes away then the relay failed. Like two years ago I lost my A/C relay I swapped it with a known good relay and A/C started working. The next town I came across I stopped in just purchased a new relay.
