Don't let your car sit (VX related)

[1993CivicVX]

Especially older cars. It's bad for them!

Just last summer my friend's '99 Protoge had serious problems after being driven after 6 weeks of sitting. Overheated and the alternator went.

Now my car has been sitting for two weeks. When I started it up it started a little rough (really only a little) but then was fine after a minute or two. 15 minutes later I drove it around the block and everything was in order. Idle was just where it should be and it sounded fine. Then I turned the fan on. Fan didn't go on. But I smelled the smell of burning rubber after I turned it on. 30 seconds to a minute the fan had been on I suppose before I turned it off. Then I did a little test. I turned it on and watched the tach and listened to the motor. When I would turn the fan on I would hear the engine go up a little. I repeated this test several times (all in the same span of time) and each time the engine note would rise slightly. So my theory is the motor is working but the fan is seized from sitting and being a really old car (everything is seized and difficult to move on my car--for instance, when I let the car sit for even just 12 hours the rear brakes seize and it's difficult to get the car to move--sometimes even the brakes seize so much the tires slide on the gravel when I try to drive away).

Anyway... maybe it'd be easy to get my fan motor unseized? Or should I just replace it?

Thanks for reading, and don't let your car sit without running it regularly!
