If our immune system refused to fight off the common cold virus, what symptoms would we experience?

Death.

Without any immune response whatsoever, the cold virus would eventually kill you. Now, if your *innate* immune system didn't mount a defense, but your *adaptive* system continued to function normally, you'd experience no symptoms. Unlike more destructive viruses like influenza, when you get a cold, virtually all of your symptoms come from your body's response, not the damage the virus causes.
