Where is the blower motor because i think it's just the wires to the blower. Sometimes when I hit a bump on the road,or closing the door hard, the front heat comes on.
The blower motor is under the dash on the passenger side.
Could be a faulty blower resistor too.

There is an updated resistor/connector package. Very expensive from GM, try your local NAPA or other parts supplier for a replacement

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

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.
