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.

GMC 2004 Envoy blows heat even with blower off ... Why ?


The relay in your blower motor is stuck on, there is a TSB for this issue. Replace the blower motor resistor and you'll be back in business.
How does the resistor get power if the fuse is pulled?
Replacing the resistor will cure both problems. TSB is a technical service bullitin seen below

Blower motor continues to run when vehicle is off


Your problem is the Relay which is encased inside the Heater/AC Resistor Module. This is a very common problem with GMC and Chevy Trucks. The Relay's return spring fails and the relay is held closed by gravity. The only fix is to replace the Resistor Module. I have a 2004 Silverado and have replaced the Module 3 times and the Blower Motor twice. The Orange wire feeding the Module is always Hot (12V) and feeds the Relay Contact for Highest Blower Speed. Hence the Blower runs all the time even with the Key off and removed.
