90 Accord EX Alternator Light and Driver Window
 

I have a 90 Accord EX.

One day the alternator light turned on while driving down the road, and the
driver side power window stopped working. All the other windows worked, no
other noticeable problems with the car.

Later that same day both problems went away at the same time. Dashboard
alternator light went off, driver power window started working.

Any suggestions as to what could cause this? No way is it a coincidence that
both failed at once and both started working at once.
