Hello and welcome to JustAnswer!
If the cooling fan doesn't come on at low speeds or stops then the a/c will blow warm at those times, but the a/c would still work correctly while driving.
The fan not working on low speed could definitely be the fan motor and if testing was done correctly then it does need a motor. You mentioned finding voltage was ok. If by that you meant there is power and ground at the fan motor when the low speed fan should be running but is not then that does indicate a failed fan motor. If you just meant you checked power at the fuses or relays then what would need to be done is test for power and ground at the motor at the time it should be running, if ok then the motor can be condemned.
