Just bought a volvo sedan yesterday(it's been 20 yrs since I owned one) It has passed Md inspection, but when I got it home once the wipers were turned on they wouldn't stop, the horn doesn't work and when you try to work the wiper control the seat belt light goes on and off.Also the headlights won't go on, only the fog lamps. I love volvo and had good experiences with them in the past, but yesterday i felt a little like Barney Fife when he bought his car. I think it is a grounding issue, and is eay to remedy.Thank you for your help and advice!!!!
