Posted May 16, 201212 yr comment_390227 First I started going through replacement brake lights, the last one only lasting a week. Now the brake lights won't come on at all. The running lights are fine, as are the other lights. Any ideas?

May 16, 201212 yr comment_390230 Check your fuse, wire connections and bulb connections first. Make sure that they're nice and clean. If that checks out then use your voltmeter to see make sure that you have voltage at those locations. Did your new bulb burn out?Chuck Link to comment https://www.classiczcars.com/forums/topic/43232-brake-lights-not-coming-on/#findComment-390230 Share on other sites More sharing options...

Put 2 new ones in yesterday...nothing. -dg Link to comment https://www.classiczcars.com/forums/topic/43232-brake-lights-not-coming-on/#findComment-390233 Share on other sites More sharing options...

May 16, 201212 yr comment_390240 check your groundsOn my 75 280Z there's a ground wire that screws into the rear body panel. You'll have to remove the plastic taillight panel to access that screw.Chuck Link to comment https://www.classiczcars.com/forums/topic/43232-brake-lights-not-coming-on/#findComment-390240 Share on other sites More sharing options...
May 16, 201212 yr Author comment_390257 I did notice a loose wire while I was changing the bulbs, but it was over by the antennae so I didn't check it (non-stock antennae). I'll check it out.

May 16, 201212 yr comment_390261 One of the contacts in the connector on my 76 lights got so hot that it melted down in to the connector, losing contact with the bulb. I assume that it started with some corrosion, creating resistance and heat. A visual check should tell you, but a voltmeter will too.

Followed by :The running lights are fine, as are the other lights.Implies that the Turn Signal Lights are working, is that the case?If so, I'd check your Hazard Switch and actually cycle it a few times. Additionally, check the Brake light switch at the top of the pedal.E Link to comment https://www.classiczcars.com/forums/topic/43232-brake-lights-not-coming-on/#findComment-390265 Share on other sites More sharing options...
