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.

Blower motor not working

I had a similar problem with my Jimmy and it turned out to be the switch on the dash. But the easiest way to rule out the blower motor is to apply 12 volts directly to the blower motor itself, if that works move to testing the switch.

I have a 1999 Jimmy that the blower motor only works on 3 and 4. Replaced the blower motor and still do not have 1 or 2.. Where do I go from here?

you need to replace a part called the blower motor resistor. it is located behind the blower motor, it looks like a wide slot inserted into the ductwork, and is retained by 2 screws. very common problem, and available at any parts store. good luck!
