I have a 2008 Mustang GT automatic. It currently has 60,000 miles on it. For the past month I've been hearing a squeak coming from inside the cabin. I think its coming from the passenger side of the car. Its most noticeable when the car changes into second gear. But when I only put the gear into first, it constantly squeaks from the start of the line. What I find weird is that when it rains, the squeaking stops. I'm really getting irritated on whats going on. Any advice would really help me out on what it may be. Thank you !
