I will admit I am in a bad mood today, and I am SURE sick and tired of various dealerships ripping people off, but you DID make it point to mention that Jiffy Lube disturbed the system (I see you now have clarified your statement - but you DID imply this started with J-L in your OP.

You then implied you had no idea what the noise was, now you say you do. YOu want someone HERE to tell you what the fan sounds like? Gimme a break, you came across rather ignorant and I TRIED and TRIED to help.

I then took the time to type out a description of how the system work so you could more understand what is going on and perhaps deal with the shop/dealer more effectively.

But now, I guess you don't need my help or anyone else's - and we are done. What I sound like is one thing, but YOU sound like a defensive fool.

Do not expect any more assistance from me.
