1999 Chevy Lumina ABS problem.
Engine size = 3.L V6
GM tech = JK
question = When stepping on the brake pedal, getting a clicking sound
like a relay is opening and closing. Brakes work fine. Remove fuse for
ABS and clicking stops. Replace fuse and it starts again. Is very
annoying. Car belonged to my deceased Dad and wish to sell but can't due
to noise.
JK:
There is really nothing under the dash
electrically for the ABS system.
Noises are the hardest to diagnose without actually
hearing it.
What you may be hearing is a loose gear in the
bottom side of the ABS motor pack. This pack is
bolted to the master cylinder under the hood, and
the sound may seem like it is under the dash.
1 of the 3 gears on the bottom of the motor pack
may have come loose because of a loose nut. These
gears spin and may be the noise you are hearing. The
cover would need to come off to check for that.
Sometimes a tech can remove the cover with
everything still bolted together, but it is very
tricky, since the TORX bolts go up from the
bottom. May be necessary to remove the ABS assembly to
get to it.
Suggest having someone listen to the noise to see
if it is in this area when the noise is happening.
Front wheels off the ground with jack stands to
simulate car moving.
