The first step is to find out why it doesn't work, there can be many reasons so start with a diagnosis.

I agree - start with diagnosis - however short of that it isn't that hard to take it out - it is located on passenger side -behind Glove box - couple screws in the plastic covering and you access the area from the floor area - also right next to the compartment filter - which you should change ever few years. Bi.ch working upside down for me, a 60 yr old. I have had to work on twice due to weird noise - which after first time I learned was a leave - fell out when I got in there. apparently crap can easily enter system... anyway - a thick leaf stem could and did in my 2nd case stop the motor from spinning. There are 3 screws on blower unit that take a tricky screw driver long and thin (may be star drive- cant remember) There is a electric plug to - easy to unplug. As you may be able to tell I'm not real techy but I could do it no problem just time (couple hours) FIRST time I didn't even take out the motor - just had spin it till the leaf and crap came out. Second time the stem was in there - dropped motor down, cleaned out stem, good to go. Hope this helps - if you drop the motor, clean out the crap - you can plug back in and check if it runs - if not check junk yards for replacement or parts store.

A problem with the blower motor resistor can cause the heater blower motor to be inoperative (no air will blow from the heater vents). Proper diagnostic is needed to determine the cause.
