My running lights, blinkers and reverse lights all work fine but when i engage my brake pedal nothing happens, the bulbs are fine as well as the pedal switch so im thinking its the relay but i cant find one for sale to save my life. Can somebody please help me?

 

I would search at Car-Part.com--Used Auto Parts Market You may have to call their 800 numbers to see if the part is there - still on the junker Z31. If you find a Z on a lot close to you, drive there, inspect the junker and negotiate. Parts you can use - for cheap(er). Keep that Z31 on the road. SHe's a treasure

Hey, the problem may be elsewhere. Z31 relays (OEM originals) rarely fail. Good luck!
