If the heater fan is not blowing on a 2001 Chevy S10 Pickup, it is possible that the fuse needs replacing. It is also possible that debris is interfering with the operation of the fan. Could also be, a faulty fan motor, a faulty fan motor speed resistor, a faulty fan motor switch,
On my 1997 maxima I had to replace it and found it in the air intake to the fan. this was under the dash. Its on a PC board and the air passing overit keeps it cool. Bob.
