The heater core in my '97 Pontiac Grand Am is leaking/broken. My mechanic suggested that, since heater core repairs are so expensive, I simply have him bypass it altogether. Since I live in Los Angeles, having heat isn't all that important for me, but is there anything else about this solution that could be detrimental for my car in the long run?

If you by pass it which is ok to do, you will also lose your defrosting/defogging ability. I live in colder region so I need to defrost my windows but if you never use your defroster then its ok to do
