Rear wiper motor on my 1998 gmc jimmy - 1998 GMC Jimmy

SOURCE: TPS in a 1998 GMC Jimmy

the tps is ususally at the side of the throttle body opposite where the throttle cable / tv cable mount.
sometimes it won't start, run, or run erratically. there are ways of testing this unit (by output voltage) before you commit to buying a new one. to test it you will need a dvom (digital volt ohm meter).

just a note: straight from the book... "a broken or loose tps can cause intermitten burst of fuel from the injector and an unstable idle because the ecm thinks the throttle is moving."

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.
