I'm giving this car-240 volvo sedan- to my son to drive from mass. back to school in arizona. I've been fixing it up a little each month. Latest problem: the right drivers electric window operates sporadically from both the driver's switch and its own switch. the horn stopped working and the high beams do not come on. All seemed to happen at once. It was caught in the rain for about five minutes with the front windows down, but nothing seemed very wet. What should I check or do, and can I fix this myself? i've just had front and rear struts done, a tuneup, four new tires. Farrell volvo is replacing the seat grid and springs in the drivers side seat, the solenoid that controls the shift, and i am having a new radiator installed in one week. It's beginning to bankrupt me.I could use some help
