All my brake lights on my 2009 Pontiac G3 Hatchback are not working. We've checked all the bulbs and they were all good. We actually just changed them less than a month ago when they blew out. We also checked the fuse for the brake lights and it was good. Any suggestions on what to do next? Trying not to have to take it to the dealership as we're not under warranty anymore.

check the ground in the fuse link also take out the rear tail light lens and make sure you don't have a broken or damage wire on the socket itself

If you have the "twilight" sensor, while there is still a pontiac, call your local dealer and have them check your VIN against the recall list for your car for Headlight relay/twilight sensor. If it is not, then see if you can check out the the combination headlight switch. I had similar problems, switch shorted out (as in smoke coming out of dash and harness melting) Dealer claimed it was not part of recall, so I paid for the Dealer to fix it 3 times--last time I had Him disconnect the twilight sensor ring and shut it off, and havent had problem for 9 years. The switch design does not have enough clearance between paths, and possibly tied in with over currnt from the relay and a bit of dirt allows the switch to short out... last time dealer had to splice in a handfull of wires (Since a new harness is very expensive). Note: Am not a mechanic... this is just an educated guess.
