After lifting the caps off I lifted the yellow wrapped magnets off of the valves, which is one piece and then cleaned the base that the magnets sit on. I pulled the valves out careful not to lose the springs sprayed them with a lubricant and reinstalled. Put everything back together and now I have AC and control of my cabin temps.
Thanks for the final answer to your problem.
One question, when you take the aluminum caps off does the coolant leak out?
I polished these caps and I did it with them in place as I thought they would leak.
Just as an aside, there is an article that I copied that shows how to repair the actual valves in this unit using Pop Rivets. It would save a lot of money if you did this fix instead of buying a new valve. Click here.
