Turn signals on vw passat 2002 are acting up sometimes they work sometimes they don't same if using harzard could it be a faulty relay btw where they?

the same relay is used for both the turn signals and the hazard lights. Carefully pop out the hazard light cover. behind that is the actual relay. Pull that out with some needle nose plires and simply reconnect the new one. You might have trouble with the connecting end staying in place(i did) so play with it for a while until it completely comes out. Remember to pull on it slowly, it will eventualy give. If your not to sure about how hard to pull then you'll have to remove the glove box and reach around the tight area you have and get a feel for the cords. the relay cost about 26 dollars at the dealership.
