How do I replace a 1996 GMC Jimmy SLT Blower Motor?

SOURCE: How to uninstall a blower motor on a 1999 GMC JIMMY

Yeah if you have to tap on it, then that means the brushes in the motor are worn out and you need to replace it. The blower motor is behind the PCM and Coolant Overflow bottle. If you remove these then it will give you better access to motor. You'll have to cut around housing. There should be a groove already there for you, just make sure you don't cut all the way around it. Once you open it and get the new one installed, you'll have to use caulk to seal where you cut it at.

SOURCE: 1996 GMC blower motor only works on high speed.

more than likely yes the resistor

SOURCE: heater blower motor sometimes works

The problem is usually with the motor itself. If the blower will not come on, tap it with a hard object to see if it works. If it does, the problem is in the motor and it needs to be replaced. Many times it is a result of weak springs holding the brushes to the armature commutator.
