Question type: Maintenance & Repair

I was driving the other day and heard a clicking sound by the right passanger
side like the signal was still going and I looked on my dashboard and saw no
signals on. But I keep hearing this and what my question is is this the signal
flasher relay that is causing the problem?

Two possibilities. The greatest is a defective blend door actuator and this would be expected in a car that old. You probably hear it the loudest behind the glove box. The other is a defective Body Control Module; they're in that location. Could be a bad resistor or relay and that would necessitate a BCM replacement. Get these possibilities checked.
