Fuse pnl under the hood. 3 fuses are marked " TRS LP, TRS 3/4, and TRS2/TCC"

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Ah, the mysterious world of fuses—like tiny gatekeepers of your car's electrical kingdom. In your 2000 Saturn SW2, those fuses labeled "TRS LP," "TRS 3/4," and "TRS2/TCC" are related to the transmission range switch and torque converter clutch. Essentially, they help manage the transmission's shifting and lock-up functions. As for whether they should have power with the ignition on, the answer is yes. These fuses are part of the circuits that need to be active when the car is running. If your car won't start, it's worth checking these fuses to ensure they're not blown. A blown fuse could be a sign of an underlying issue, so if replacing them doesn't solve the problem, it might be time to dig a little deeper or consult a professional.
