I know this is
and all, but I wanted to get some help on a problem with my parents Grand Cherokee. They were out today and said they heard something like glass smashing. My Dad didn't think anything of it so he kept driving. About 10 minutes later it started to overheat. He also heard a clicking sound that got louder and faster as he accelerated.
Any ideas on what it could be? If you need more info I will try to get it.
