I e tested 4 now and after 10 min none of them close completely or at all. Either way could it be because of a bad connection? Not hot enough? I know atleast one, the newest one was tested as good and is very clean. I know they can go bad inside but I do not think they all are.
But after 10 min of car at idle its still pulling air thru, suggestions please. Phil |

They get pretty warm, and the heat from the case adds to that heat to close it off all the way.
Most I have seen are just full of junk that gets in the way of the spring closing... Even a little chunk of junk will stop the spring from coiling up all the way...so the AAR will stay open a crack. Rich |

Rich I m going to bench test them tonight, see if the warm up and close up- but from what i am reading here and on the ander's site i think he says 10-15minute it can take to close up, i have not run the car long enough, but i will also test the 12v going to the unit from the harness and the fuses as well, and will report back. Anders also discribes being able to change resistance to change the time it takes to warm up and close, i'm not going to mess with that but if the 12v is there ,on this new one it may be that it sat in a box for 21_+ years on the shelf, and the soaking in penetrating oil might do the job to loosen it up.
