i had problems with the dome light not coming on, or if I started the car with it on it would stay on, my defroster stopped working as did intermittent wipers. When I disconnected my battery to do fuel filter it went away. at the same time I pulled the relays out to try to check them but I didn't know how to check them so I just stuck them back in. The car has been fine ever since. Mine is a 99 v6 MTX
