Car news....maybe

So I just got a call from the dealership. They're pretty sure they've got it fixed. Long story short, they figured out it's a "feedback" type noise (exactly what my husband had been telling Hyundai for how long?) Oh sorry, I digress: so they disconnect the alternator and later remove the two right front speakers. After 2 hours they test it - no noise. So they put the speakers back and 2 hours later - still no noise. SO, the guy will test it again in the morning and let me know for sure but it had been doing it after just 2 hours outside today at the dealership so all signs point to YIPPEEE! I told the service guy if they had fixed it I would sing their praises from here to timbuktoo! (And yes I'm sure I spelled that wrong.) He said he called the service line and the printout we had given him of the history (3 pages long) was nearly word-for-word what Hyundai had on file, he was AMAZED that no one had figured this out before......he's not the only one!!!!!!!!
