2002 GMC 3500 Short Bus Switch panel

[katiejay99]

Hello. I recently bought a 2002 GMC 3500 short bus, Thomas Built. 2 days ago I realized that everything on my Switch board above my drivers chair is not working. I don't know if it is the switch board or not because my brake lights are not working either. I have no rear lights except my emergency flashers and my directional signals. Also my interior lights and rear heater are not working.

I have no idea what to do. I have checked all of the fuses and they appear to be working (I can't get to the ones under the hood of the bus). I did remove the negative cable on the battery and reconnect it but that didn't help either. Stepping on the brake will cause a clicking sound above my head and to the left inside where the relay switches are.

Any ideas? Thank you in advance.

check the circuit breaker. it should be under the hood off of your main battery. there will be a little black arm that you need to press back in to reset the breaker. should take care of your issue
