Rear break lights and blinkers on a 2000 Denali
I have a 2000 Denali my rear brake lights and
blinkers do not work but they work on the
front and my tail lights work I done change
the multifunction switch and it still won't
work what could it be
Try changing the bulbs.
Thanks I did they all new still nothing
Then follow the wiring from the rear tail light lens back to a plugin, there may be one on both sides. Should have something to test for power at the connector like a test light. A lot of times these connectors loose contact. See if the problem is there.
Thanks I done that all so
Well then your killing me here...lol. Is there a circuit board in the tail light lens? Those go bad.
Lol sorry man I swopped out one hole lends thinking that may work too lol it's got me puzzled
But you have power back there to the plugin? Look for and check and clean up ground wires.
Check and check Grrrr nothing seams to be working
