Saturn 2001 SL idles in neutral between 2000 and 3000 after engine gets warmed up. also blower for heater has bad resistor were is it located so i can replace it?

screws on the top of the dash in the Saturn. Then pry the dashboard up and away. This may seem like a pain to get to, but it's a must if you want to fix the heater blower motor resistor.

When engine is warmed up to normal temperature, feel both heater hoses. If both are hot, coolant is circulating through the heater core. Could be a heater case door not opening. Does blower fan work?

High idle speeds on modern engines is in most cases caused by an engine vacuum leak.

There are 2 different engines for the 92 SL,they are 1992 Saturn SL 1.9L TBI SOHC 4cyl 1992 Saturn SL 1.9L MFI DOHC 4cyl Here's a link to the blower motor resister,it's located next to the blower motor,2 screws hold it on.

this resistor is located on the lower rightside of the dash, it is next to blowermotor and is in heater box, this part slides into heater box and is held in by two screws, its like a T it slides into the box and then the top of the T sits outside the heater box and two screws hold it, heres a picture of the resistor , hope this is helpful.

check the hvac fuse. if its ok you can check the heater control resistor. its mounted in the heater box usually on the passenger side under the dash. these are cheep and available at your local parts store

i had that problem, you need to get your head gasket replace.

I would take it to autozone to have the code read. It could be your idle control sensor, or it could even be O2 sensors. Hard to say without knowing the code.

The problem is the blower motor speed control resistor, it is located near the blower motor in the housing.

Hi,

The fuse box for a 1995 Saturn SL would be on the passenger side kick panel for most of the electrical devices inside the car. However, there is also a fuse box in the engine bay near the battery.

In some instances, an A/C (heater) fan (blower) failure could be caused by a defective resistor.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
