Why does my TCM fuse keep blowing out?
Why does my TCM fuse keep blowing out?
The fuse isn’t blowing because there is no defect, and nothing to find. Grrr. You have a permanent short which is a real lot easier to find because you will know exactly when you do something that makes it go away. The bulb will go out or get dim. Start by unplugging items in that circuit.
Where is the fuse on the Transmission Control Module?
The Transmission Control Module is labeled “TCM” it’s easy to find as long as you know the abbreviation. Where is the 4L60E fuse? You’ll find the fuse to the 4L60E located under the hood of the car or truck. It won’t be in the fuse panel that you’d think of when looking under the dash. It’s under the hood, usually on the driver’s side.

Why does my ASD fuse keep blowing out?
Most blowing ASD fuses revolve around shorted oxygen sensor heaters or the wiring going to the oxygen sensors. Look for a wiring harness that fell down onto hot exhaust parts. If everything looks okay, unplug the O2 sensors, then if the short appears to be gone, reinstall the ASD relay and fuse then try to start the engine.
What causes a fuse to blow on a test light?
The short is bypassing that resistance. With no resistance to limit current flow, that current will be much too high, and the fuse will blow. Your test light or my test bulb has resistance. By sticking that in the circuit where current has to flow through it, the bulb limits current flow to a safe level.
What to do if your ignition switch fuse keeps blowing?
A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a twelve volt light bulb. A brake light bulb works well.
