Well, it wasnt the driver side that went out on mine, it was the passenger, but still the same idea. First thing i would do is check your fuses. If that isnt it, it could be the power window motor (which could be, but rarely happens) or the master switch (which is what was wrong w/ mine). Honestly it could be something as simple as a stripped wire. Hopefully you find out whats wrong and fix it before the rain hits.
