Hi Scotty can you help me? My ac have issue its blowing cold only at passenger side and now the whole ac is not working. The mechanic told me there is a leaked and need to replace the evaporator is it correct?

if evaporator is leaking, yes. and they often go out that way when they do

So the reason why my ac go out that way is because of evaporator leaked..and need to change it not repair the evaporator thanks a lot
