Question about 1997 GMC Jimmy
There is a heater box just above the passenger footwell, and behind the glovebox. generally the fan is installed upside down on the bottom. so if there is not a wrap under dash you can put your head where the passenger's feet should be and look up. above you will be the cable connector and screws holding the fan into the box. if you disconnect and unscrew it, pull it down out and replace it. Take a few extra minutes and put a canister vacuum hose up in there and **** out whatever you can get in the way of leaves and gravel so they do not get into your new fan. Be gentle, if you are ham fisted let someone else do the vacuuming for you. do a quick search for a video of this process on www.youtube.com there are thousands of car repair videos there.

Hi. The removal is really easy; unplug the motor under the glovebox, and remove the 3 screws that holds the assembly in. You can have it out in 10 minutes.

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.

On my 1998 GMC Jimmy it is under the hood on passenger side on firewall behind the PCM (black box) which is mounted on top of coolant overflow bottle. You'll have to remove these two items for better access or at least the PCM. Then you have to cut the moulding on the blower motor housing. You should see a groove already formed all the way around the housing and this is where you have to cut. Just don't cut all the way as you have to reseal it with caulk once you are done installing new motor.
