What else do I need to check to find out why the brake lights do not work?
Things that have been done:
Grounding good, bulbs good, all fuses could find are good, all connections
could find are good, brake light peddle switch replaced with a new one,
blinkers, running lights and backup lights work on both sides, No voltage
present at the connector on the left and right tail light assembly when brake
peddle is pushed. Top center brake light works.
got to be a connection some where after the brake switch...but some of that stuff runs through the turn signal..
Is there a relay in this circuit?
I had the same problem in my chevy malibu I had to replace a relay under the hood it cost about 20$ at the dealer
