I took my wife car to the shop to get a head gaset replace when I got the car back my wife notice she has headlights but no taillights or instrument lights. her bell alarm goes off, as if the headlights were left on, but they aren't I checked the fuses but all seems fine I need to now is it some thing I can fix because my wife is driving our children aound with no ligths and I need her to be safe.
no backligths on 2002 Pontiac Montana
If the fuses are OK, then you'll need to have an electrical system diagnosis performed, and this is best left to someone with experience. I would take it back to the shop that just did the work on it.
