Ok - Help? What do I check first - about a month ago, my turn signals went out and magically came back on about 15 minutes later. Yesterday, my tail lights and brake lights no longer work...The turn signal wand doesn't even click anymore so I don't think it's a bulb failure..? I had hoped I'd get up tomorrow and they'd magically come on again - they did - for about 5 minutes and now they're back out again and seem not to be inclined to work again. Complete novice at mechanics, is there any point in trying to find the problem or am I better off seeking a professional??
