I found an very old, very short post about the subject and cleaning the AAR with PB Blaster. So I guess I'll try that. But that post did not answer my current problem.
I have had my AAR off of my car and the hose connections plugged for about 6 months now. But it is getting cold and it has been recommended that I put it back in service. So I tested it. And took some pictures along the way. I did the FREEZER test and it opened.

I sat it in the sun. Very warm exterior case. Kinda tuff to hold it. It absorbed a good bit of heat.... and almost closed.

Then I broke out my handy dandy 12v drill battery and within a few seconds it was closed.

here is the question..... I tried to blow thru the closed hole and had ZERO problem doing that. So I suppose when closed that NO AIR should pass thru, correct? Will the PB Blaster cleaning help, or is this baby done for? Any ideas on fixing?
Thanks.
