Hello, I have a 99 XJ and recently I have noticed a very agitating squeak coming from the passenger airbag/firewall when at highway speeds or going over rough road . I have removed the center bezel and placed friction tape everywhere I could yet it has made no difference in the noise. I have noticed that the noise increases greatly once the engine is up to operating temp. Anyone who has any input on what could be causing this or how to fix it would be greatly appreciated
