I have an 02 TJ that is experiencing a few different issues and I am not sure if they are related. For starters, the power steering seems to be sluggish to get going when I first start out in the morning, but once it is going it is fine. This is coupled with the defroster and vents shooting out air no matter what the setting is. I know the defroster issue is probably a vacuum leak, though I can't find one. I was just wondering if these two could be related and if there is a certain area under the hood I should be checking. Any help would be greatly appreciated.
