Question about 1999 GMC Jimmy
I have a 1999 GMC Jimmy sometimes the heater blower motor works and sometimes it doesn't. It comes on sometimes when you are driving it .
Where is the motor as i think its burnt out.

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.

Check to make sure your wires are connected if so you may need to replace the blower motor

Fan motor would not run same time as "2H" lite was out.
Not sure if these are related, mite be coincidence, but:
This is either a blown fuse, a loose fuse, dirty or destroyed contacts behind the fuse, or a loose/inttermittent ground/wire.

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.
