One problem related to fuses and circuit breaker has been reported for the 1998 Volvo V70. The most recently reported issues are listed below.
This car has been plagued with electrical problems. Headlight, taillight, turn signals. . . All have been replaced numerous times. The stereo and battery have also been replaced. Both the drivers window and the rear passenger windows have malfunctioned causing them to "stick" in the position that they are in. The dealer has replaced most of the bulbs at no charge. I have had 2 replaced while on vacation at various times. I can not think of anything other then the tires, that is not governed by the electrical system in this vehicle. With two small children, this is obviously a concern to me. Volvo as a manufacturer has promised a full system check two times. It never happened. At this point, I don't know that I would trust the car even if it did check out ok.
