Ok this is really weird. It doesnt happen all the time but my brake light go out and third light will work. Then they will work but the third brake light wont. Checked switch, lights connections front and back. Any ideas?

Thanks

 

bump^^ Any one know what i may be missing?

 

Sounds like a grounding problem. Just an opinion though.

 

Just got a call from my worker and now he has no blinker and a buzzing noise from the dash behind the radio when brake is depressed. I am thinking there is a relay or light control box behind the radio. Anyone?

 

I just had a problem (2X) with brake lights, turn signals when the lights were on. they replaced a relay the 1st time and it came back a week later. Master tech thought it was light switch or blinker assembly. Turned out to be that the 400 ground was either not hooked up or was not tightened. Dont know where its at but your dealer will. I think it may be behind the drivers kick panel but am not sure.
