how to change the a.c. filters on 2000 BMW 740i

the filters are little square filters

Asked by for the 2000 BMW 740i
There are three filters one under the hood and two others real easy to change. Look on Youtube I think I saw videos there. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
