Question about 1999 GMC Suburban
How do I replace blower motor and dashboard control panel on 99 GMC Suburban
I never read that the fuse was blowing in any of the descriptions, but if we are going to jump ahead and suppose the armature is shorted, wouldn't it be easier to just pull the plug off the motor and replace the fuse and turn the motor switch on and see if the fuse pops after we have eliminated the motor. If fuse does not blow, the motor is bad. If fuse blows, you have a short somewhere.
In my experience, armatures usually fail open and the motor simply won't work. I still stand by my suggestion of step by step methodical troubleshooting rather than buying the parts first.

There is too much resistence in making the motor run, ie.friction and cold,dried grease in the bearings and this is equilent to a shorting the brushes on the armeteur which cannot spin fast enough to move from contact to contact internally as it should when running normally. This is what is blowing your fuses. Unfortunaltely, you will have to remove some ductwork and perhaps the glove box to get to the blower motor. You may be able to restore it, if not, ck your local junk yard and compare prices with a new one and if you plan to keep the unit indefinately, you may wish to spring for the new one.
