QuestionLately I've noticed that my parking and dash lights flick when I use my turn signals. It's not necessarily the fact that I use the turn signals as much as the fact that I move the switch. Sometimes the slightes touch sets the lights off. I tab it again to switch them on. This only happens when I have either my parking or headlights on, so not during the day...only at night. I'm thinking there's a loose connection, but I'd appreciate your opinion. Also when I turn on the heater/ac fan it sounds like there's something falppin' around in there; there's also a clicking noise coming from the wheels, but there's nothing stuck on the tires, maybe the hubcaps? Sorry about the last two questions, just wanted to get them off my chest.
AnswerFirst, regarding the lamps, you'll almost certainly need a new switch. I only recall one car recently in service with a switch electrical issue, and I remember going to the parts department with the old one, and they didn't have a new one. So I pulled the cover off to look at it and found that there was an electrical connector inside the switch that had come loose.
As for your climate control blower, there probably is something flapping around in there. Usually it's a leaf or something similar. If it bothers you enough, you can move some electrical wiring out of the way, remove the three screws holding the blower in place, and remove the whole assembly out the bottom of the heater box.
As for the wheels, it's hard to say. But you may want to check the brake pads. It's possible one of the wear indicators is rubbing.
