I just bought this truck the other day. The brake lights don't work at all. No lights at all, for anything. The turn signals aren't blinking fast like they would if a bulb were blown either. I'm not really sure where to start with this. If anyone has any advise on where to start I'd really appreciate it. I'm familiar with a multimeter and have one for work so I just need to know where to start. Thanks in advance for any help!
