i need to replace the blower motor in my 1996 Audi A4 2.6 V6 Quattro and i have a choice of 2 but i'm not sure of the part number of the one i need. i'm going to fit it myself and i'd like to know how easy it is to get to it. apparently i need to take the glove box out and it will take approx 30 mins to replace it. can you tell me if this is correct? many thanks for your time and help.
