I have a 02 ssei with the dual digital climate control and to get a trickle of heat i have to turn the fan all the way up and it makes a weird spinning noise under the dash on the passenger side i believe the blower motor is going out. so are there any step by step directions on changing it out and is it worth it to do it myself because i have been suffering this michigan winter with only a seat warmer

as far as the noise you never know. mine been making noise for a few years of 24/7 use. apparently my wife doesnt realize the windows roll down.
