On the 2002 L300, there is a relay module mounted in front of the battery. Inside is a circuit board with relays, diodes, etc. GM still carries this part and it called a fan relay module. However, if you trace the leads, they go to the headlights, marker lights and turn signal lights. It costs about $200 and unfortunately, the components are soldered into the board so the entire module must be replaced.

I have a Saturn 1992 SL Sedan with 164,000 miles. I am having a major problem with the car cutting off while I am driving at a fairly constant speed or when I am idling at a stop light. The engine will shut off, along with the power steering and all other electronics. This happens when at a stop light only after I press on the gas to accelerate from a dead stop, but I am able to put the car in neutral and start the car again (sometimes it takes a while to restart). We tried getting the electronic control module repaired, but this did not fix the problem. We checked the oil and it appears to be of the correct viscosity for the engine. We are at our ends as to what needs to be done to fix this dire problem. Thank you for your time! 8 Answers
