Question: Last year, I bought a 2005 Volvo S60 for my wife to drive to her job.

The car had 103,000 miles on the clock, so a few weeks ago, I installed a new timing belt, tensioner, idle pulley, and water pump. In order to complete the installation, it was necessary to pull the power steering fluid reservoir off to the side to gain the clearance to remove the timing belt. The timing belt installation was completed without any serious incidents.

I was also advised by a mechanic that the car needs to have new lower control arms on the front, as well as new joints. He said that the joints are "slinging grease". I don't even know exactly what he meant by that.

I inspected the hoses on the power steering fluid reservoir as best I could, but I can't see that it's leaking; I really have not idea how the car is losing its power steering fluid.

I have refilled the car's power steering fluid twice in the last week. What is the best course of action to take to find the problem and get it fixed?

Answer: 
As for the blower only working on max, that screams [resistor pack](http://www.rockauto.com/catalog/raframecatalog.php?carcode=1424405&parttype=6557&partkey=2194770&a=FRc1424405k2194770-2899550). It's usually in the passenger foot well near the blower motor itself. [Sounds like](http://www.chryslerforum.com/forum/chrysler-sebring-14/blower-motor-resistor-diy-2004-sebring-sedan-8772/) it's held in by two 8mm bolts in your case. Shouldn't be too terrible of a job, but you might want to avoid it if you've got back or neck problems. I usually put the seat back down as far as it will go and lay down facing forward and pull myself up under the dash. If you've been running the blower exclusively on high for a while, it might be the next thing to go out. Last time I changed a resistor, the blower worked for a couple days then died. That was a little more involved, but still doable if you don't mind being upside down in a tight space. 

As for the temperature falling off, the two things that come to mind for me are maybe a clogged heater core and / or thermostat. What are your engine temps like?
The heat problem sounds like poor coolant circulation, possibly due to low fluid level or partial clogging.
