94' F355 Lighting and A/C fuse problems..

My 94 3f55GTB has developed two problems. The 30a A/C fuse next to the blower will violently blow after about 10 minutes running time on initial start. That time is reduced to about 2-3 minutes once the first fuse blows. All subsequent fuses blow in about the same time. My thought is that the blower motor bearings might be partially seizing after a few minutes running time...although the squirrel cage seems to rotate with only a moderate amount of resistance after blowing a fuse. Any ideas?

Second problem involves the parking light warning lamp and park lights themselves. Suddenly and without warning those three lights will not turn off. When the light switch is in 'O' position (lights off) the green indicator stays on along with both park lights. The only way I've been able to turn them off is by removing the fuse in the box beneath the passenger side foot board. I've been unable to locate a relay in the system either for park or headlamps. I do not have an owner's manual or electrical diagram at the moment, so any help/advice/suggestions/remedies offered will be greatly appreciated.

Thanks in advance..
