2002 chevy s10, a/c fans won't blow Sign In

i just picked up a 2002 chevy s10 pick up from my grandfather. he told me that the a/c and heater were not working, and that the problem was probably as simple as a blown fuse. so i decided to check it out for myself......
here's the deal. the fans wont blow at all. i know the compressor is still working because it gets cold.
so, i checked out every fuse labeled hvac and none appeared to be broken. still i changed them, but had no luck. the fans still won't blow.

is there something i'm missing here? (that's rhetorical. i obviously am.)

any help would be greatly appreciated. please keep it simple, i'm just a beginner with this stuff Smile thanks!!!

Here is a diagram of the electrical circuit. Look on the left side of diagram. It has the main fuse, relay and blower motor. The fuse in in the underhood fuse box. Then the relay and blower motor. Check at the blower to see if there is current going to the motor. If there is current, the motor may be bad causing the problem. If there is no current at the blower, check the resistor. If there is current there, check the relay and if there id current there, go to the fuse under the hood. Hope it is not too confusing.

Being way2old is why I need help from younger minds
