    1) when at a stop light. my lights dim. as soon as i start to go. they get bright again!

    2) i have a hissing sound coming from that side. no noise while just rolling. but when i'm on the gas pedal. i get a hissing sound?

    thanks in advance!

    got a volt gauge?

    it's possible that the alternator is gone.

    Yeah mine did that...every time I'd get to idling it down dim...I'd lose about 2 volts watching the volt meter. I swapped out the alternator after about a week of dealing with that and now I sit just over 14.5 Volts...so I am happy

    Yeah, thats still a lot. Not as bad as the extended warranty commercial $1800 to replace an alt?

    the dealer will charge hours of install and parts...so when looking at a job like your it was probably around 30 min job so about $60 in labor and $375 in parts?...

    so $488 is a lot. compared to buying and installing yourself which would run about half or less...i am not a fan of stealerships. i think they just rip you off! but you had your warr. so you got away good.

    Yeah the only way I would take my car to the deal is if it was under warranty like yours. Rentals are fun! The $1800 I saw on a commercial. This company sells extended warranties, that was one of there selling points. I have no clue what they are driving that it would cost that much. Maybe a Prius?
