Perhaps ther  bearings in the fan are going.  When it runs a few 
     minutes the bearings heat up and expand, slowing down the rotation.  
     Once cooled the same process is repeated.
     
     You might be able to find one mail order or in a junk yard.
     
     good luck

Does anybody have a clues as to why my front heater fan doesn't work 
right? It will occasionally go on a few minutes into a drive and then 10 
minutes later it will start to "die". It will start to slow down, and in 
a few minutes it will quit. It won't start up again until it feels like 
it. Usually a few days later Same thing every time. I think my parent's 
checked it out at the dealer once and the dealer said that we needed a 
new ($$$$) fan. Too much money.
     
It seems more like the problem would be electrical. I tried a new switch, 
but the same thing would happen.
     
Any Ideas?
