The front driver window was making a clicking noise as if it were coming off the track. Eventually, the arm motor stopped all together and I had to replace the arm. Now the front passenger window is making the same noise and I'm afraid to open it. The leather interior is cracking badly on all seats. I rarely have passengers and condition the leather. I've had to use an adhesive to prevent additional cracking.
