I have a 1987 Volvo 245 GL. Recently, the radio, wipers and horn all concurrently would not function. I cleaned the fuse holder and replaced the fuse which seemed to have solved the problem. Subsequently however, the horn and wipers worked properly but the radio did not function or the radio functions but the horn and wipers don't. Could it be a grounding problem somewhere? Additionally, now, the headlights sometime do not function when the horn, wipers and radio are all out...

Any thoughts will be appreciated!

Thanks.
