13 780 d13 clutch fan/dryer problems

This morning after an hour in cold wet conditions I noticed my fan was on and my dryer is "unloading" every 30 seconds. I assumed I had some frozen moisture in the system but it's above freezing now and it still continues. I have a load to deliver so my questions are
1. Am I hurting anything other than my fuel mileage?
2. Any guesses what the issue us?
I assume the dryer issue is my govener, but would that effect the air to the fan?
Thanks! !

 

I don't have a fan switch and I couldn't figure out if they are connected or a coincidence? It did this last week but stopped once it warmed up, it is planned on a trip to service next Tuesday for some unrelated stuff when I get home but that's a couple thousand miles away. Was just wondering if anybody had seen the Same things.

 

Air it up and shut it off leave the key on and no air leaking??

 

Fan hub bad. Had it replaced at a shop recommended by volvo dealer in kankakee il. Mechanic did a good job, tho the guy running it was an ###hat. River Valley truck repair. His credit card machine wouldn't take a Canadian Mastercard......called his provider who tried to do it manually but he couldn't get it thru. I called my Canadian bank who said it was all good no problems on their (my) end. So then look for a bank mschine to get a cash advance, run into the $400 a day cash advance from the machine, I need $800...... go find another, declined, $400 American is over 500 canadian, so now I'm over the $1000 per day cash advance on my card... go to a bank, can't remember the name of it, small I guess as they can't read ANY of my canadian cards (am I in Afghanistan? ) so off to a major bank where I have no problem getting another $400 from my savings account. (We're 2 hours in now) back to the shop, I ask him for a little off the bill for my inconvenience, as it was his card machines fault (more on that later) and he gets even more ignorant than he was when "my" card was declined. So I pay him in cash, eat all the associated fees and time and head out. Here's the best part, .... I get a call from Master Card fraud detection and they are checking on my card and all the action on it. I explain all the issues and that I'm not happy a Gold Mastercard wouldn't work and she goes into the transaction and opens it up. THE IDIOT PUNCHED IN THE 3 DIGIT CODE FROM THE BACK OF THE CARD WRONG..... if I wasn't already an hour away I would have gone back.
Anyway, good service, expensive, and the guy running the place is a cranky ###.

 

Yes they couldn't touch it for at least a day.
