Sorry but your question is way to vague.

It's on the backside of the motor if you stand on the drivers side and look down on the back side of the motor you can just see it the best way to get at it is put the car up on jack stands get under the car it's in the middle of the back of the motor.
Good luck

Look where the throttle cable hooks up to the throttle on the throttle body,it is no the opposite side,it moves with the throttle,if this was helpful,please rate,thank you.

For 1999 Saturn SL2 1.9L MFI DOHC 4cyl the FLASHER is located seating area, center, under dash, mounted under center of dash.

Hope help with this (remember rated this post).

you must remove the steering wheel,air bag and the clock spring and the the whole switch,no easy,way DO NOT DO if you do not know how,you could set the air bag off or mess up the clock spring position and wreck it,,,take it to a shop,if you are not familiar with this kinda repair

It is located on the transmission side that faces the front of the car. It's just left and below the transmission spin on filter. It's the same sensor for the Engine Coolant Temp sensor and the Intake Air Temp sensor.

bad idle air control valve or a misfire,could be alot need more info

the coolant temp sensor is located on the right side of the cyl head its small under by the upper rad hose 13mm socket removes it after u take the small connector of,make sure the car is cold coolant will come out when u remove it,,,,check the connector too for corrosion,by only saturn sensor the cheap autozone and aftermarket ones dont read right and give you the same problem as the old bad one
