Conversation Between infinitiman96 and aikensre

hello, i have an infiniti i30,99, are parts from i30 96 0r 98 interchangable? and if anyone has any imput , ill take it, my ac/heat only blows when it wants to, if i hit a bump, it may work for the duration of my 30 minute drive, i may hit another bump and it goes off. so obviously the blower motor isnt out, but there is definantly something wrong. it doesnt work most of the time. please help!!!
