My AC light's and radio light's act very weird IF they even come on. Sometimes on, sometimes off, sometimes they just dim in and out, in and out, in and out. What should i check because i think this car has serious electrical problems. Sometimes the courtesy light on the driver door wont come on when i open the door so i have to hit it. Please help

 

loose connection somewhere...maybe your fuses are about to fall out? That's all I can think of
