Blower cuts out

[k98dave]

Been having a problem my fan motor (internal A/C/Heat fan) it shuts down every once in awhile. Seems to only happen when its on high for a long time. Checked the fuse when it first quit but it was ok. Happened twice over the 2 weeks and again today, checked fuses again-OK Turn the car back on and its fine.
Any suggestions on what the problem might be?

Thanks

Pretty much narrows it down to the switch, the speed resistor, assorted wiring, and the fan motor itself.

Maybe get a tet light onto the harness sectin that feeds the motor and see if it goes dark when the fan stops? Might help with the troubleshooitng.

Thanks,

I'm going to change the fan resistor module since its easy to get to with one I have from another car and see what happens.
