not sure if its a wiring issue or anyone else has had this problem but my tailights reverse lights head lights all work but when i press on the brake the brake lights wont come on tested all the fuses and checked the bulbs anyone know what the problem might be? this is on a da9

 

Check brake light switch. 94

 

how can u tell if it is bad or should i just replace it?

 

pull the bulbs first and inspect them... 1 filament can be bad..if they are good change brake light switch

 

Unplug the brake switch and jump the two leads in the plug, [white/green and green/white] if brake lights work replace switch. 94

 

thx guys got it replaced this morning and everything works!!!
