I have a 99 Chevy Blazer with a driver's side brake light that has become possessed and only works when it wants to. My dad has attempted various fixes which the light will work and then we notice later that it is not working again. Can you suggest anything? Do you have the breakdown of wires on that side for the breaklight? And my hatch release button has now stopped working and my key is also not working so I can't get into my truck, any suggestions? Please help, I don't want to pay labor fees to a shop and my dad is clueless at this point. Thanks.
