Hi, welcome to Just Answer.

Is this the 30 amp F14 fuse in the front power box?
Thanks, What you need to do is remove the door trim panel and disconnect the driver side power window motor. It may be shorted which is why the fuse blows when you press the switch. If after disconnecting the motor the fuse no longer blows, replace the motor. If it continues to blow, let me know and we take it from there.

You need to use trim tools like the ones sold below on ebay...

Below is the procedure to remove the trim panel...
WARNING: For models with airbags, follow safety instructions.If work is carried out in the area of airbag systems, e.g. on:Door trim panels Interior trims Instrument panel ect. the ignition must be turned off in each case. The ignition must always be off. The ignition key must be removed from the ignition lock. This eliminates the risk of injury
CAUTION: DO NOT use any sharp-edged tools to remove the panel (risk of damage to side airbag)
Lift off cover, remove screw and window winder. [IF EQUIPPED]
Installation Note:
Convertible and Coupe:
Sedan and Touring:
Installation Note: After fitting the door trim, proceed as follows:
Ooops, I forgot to tell you the screws are Torx...you can pick up inexpensive Torx driver sets for around $10 at moxt any hardware store or Sears...they come with different sizes on screwdriver type handles. Take your time with the door trim panel...after you do it once or twice it only takes 5 minutes to get it off...and BMW trims panels are good experience for all other types of panel removals.
Thanks for the ACCEPT, i'll still be here if you run into any trouble.
