2009 Pontiac Vibe Question: My 2009 pontiac vibe turn signals do not work in heat

my 2009 pontiac vibe turn signals do not work when it is warm out. the regualar headlights don't work either, although the daytime running lights do work and then headlights work when it gets dark out. Very very frustrated. Have taken it to the dealership but when I get there everything works and so they find no issue..ugh... -
