BMW Repair: Cabin Air Filter, cabin air filter, 1993 bmw 525i

Question
1993 BMW 525i Sedan...where is the cabin air filter and how do I change it?  Or is the change out pretty simple/self-explanetary?

Answer
The cabin filter is behind the glove box. you must remove glove box then a black air vent that is L shaped a plastic cover also. once those are removed behind the evaporator box you will see a black cover with a turn key type handle turn it remove a torx 20 on the bottom of the cover you then remove a module that is also behind the evaporator box you can then remove the filter, pay attention to how it comes out the cabin filter only goes in one way, this job could easly take over 1 hour +,   Its a little tricky so good luck.     Thanks Nathan
