Niner cooling system issues...

Started noticing that i was overheating about a week ago, it was intermittent so i thought it was the thermostat, so i replaced it, and it still continued. i did the paperclip jump and found that both relays work as well as the fan. but while driving i never heard the high speed fan kick in, only low. figured it must have been the high speed switch, while unplugging the clip i noticed the inside was all corroded and pretty much nothing left, figured that was it, wrong again
so today on my way home i noticed that it got warmer then it has in the past so i did the paper clip thing again and the low speed fan wont kick in but i can hear the relay click, high speed works fine
i got the new high speed switch so im gonna do that as soon as it cools downs but as for the low speed could it be the motor?
if so where do i get that at, no parts stores around here have no...

Thanks in advance for the much needed help
