Exterior and interior lights as well as the blower fan lose power which makes the lights dim and the blower slow down. Dealer installed a capacitor and positive battery cable shielding as per their bulletin, but this did not correct the problem. I don't believe this should be considered a normal characteristic as I have been told by the service manager on several occasions. I am afraid that one day it will totally lose power.
