AC and Hub Question
My Ex must have developed a vacumn leak. On acceleration the AC switches from the panel vents to defrost.
At slow speeds while turning I feel a clunking in the front end. It is not pronounced as if the 4X4 was engaged but it is similar.
I assume that these 2 are related. I have a little mechanical ability to work on the problem. I was hoping for some guidance on where to start. If all else fails I will take it to my buddies shop to figure out what the issue is but was hoping to save some money and time.
In searching I saw notes about the hubs switch based on a timed pulse of vacumn so I don't quite understand how a leak would cause this issue.
TIA
