Inspect the relay and fuse/relay box socket terminals
to be sure they are all making good contact.
. lf the terminals are bent, loose or corroded,
repair them as necessary, and recheck the system.
. lf the terminals look OK, make the following
input tests at the fuse/relay box socket.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the turn signal/
hazard relay must be faulty; replace it.
