The blower is located just behind the glove box...
http://www.q45.org has an article on the glovebox removal......
Basically you remove the 2 bolts on both sides... take off the kick panel, and youll have 4 bolts on both sides and 2 small screws in the middle...... Then it all slides right out... The blower motor is right there and shoudl be fairly easy to replace.....
Ive also heard of the blower relay going out, might check that and do a search.....
Your saying the ABS light is on??? I would assume the ABS actuator is bad or maybe a bad fuse.. Do you have TCS???
