Why does my tail light fuse keep blowing? I recently replaced all the rear brake light bulbs in my 2008 Dodge Charger and when I turned on the lights, the fuse to the tail lights blew immediately. I changed out the fuse and it blew again immediately. I then disconnected the shift interlock solenoid and reconnected it to see if it was causing the problem and the fuse didn’t blow but when I turned on my lights, they worked this time but soon after, the fuse blew again. What’s going on?
Check Rear Brake Light Bulbs
When you see a small light fuse keep blowing, it could be because of a number of reasons. The most common one is that the bulbs on the brake lights are loose or burnt out. This can be confirmed by turning your lights on and seeing if the problem goes away. If so, then you just need to replace the bulb(s) with new ones. If not, then you'll need to do further diagnostics to find out what's wrong with your brake lights before you can continue. Other times, it might be caused by an electrical issue with the wiring harness itself and not the bulb. In this case, you will need to take your car in for repairs as soon as possible.
Replace Shift Interlock Solenoid
If your brake lights have been blowing a fuse consistently, it's possible that your tail light fuse is the one to blame. That may be because of a small light fuse or a G35 tail light fuse keeps blowing.
To figure out what the cause might be, you can disconnect the solenoid first and see if it still blows the fuse. Once you find out what the problem is, you can replace it with a new shift interlock solenoid and get back on the road!
Your vehicle's wiring system has plenty of fuses to help prevent serious damage in case of an electrical overload. It should not take long to check them all by hand when you notice that your car isn't running as smoothly as usual or one of your electronic devices stops working properly. For example, if your G35 tail light fuse keeps blowing every time you try to accelerate hard or drive fast down a hill, then that's likely due to an electrical overload from shorting wires or excessive current draw from accessories like auxiliary lights and audio equipment.
How do you fix a fuse that keeps blowing?
If you're wondering why your tail light fuse keeps blowing, it could be one of three things. The first is that the problem lies in a faulty bulb. You should check and replace all bulbs in the tail light to ensure that's not the case. If you've done this and your tail light still blows, then there may be an electrical short in the wiring. Disconnecting the shift interlock solenoid will tell you whether or not that's true. If disconnecting it doesn't blow the fuse, then replace it with a new solenoid.
*How do you disconnect a shift interlock solenoid? * Disconnecting the solenoid can only be done if it has been disconnected before. Otherwise, you'll have to remove the entire shifter assembly which includes removing the rear seat back. After removing these items, remove four screws on top of the steering column to access the bolt connecting shifter and remove bolts connecting harnesses on each side of the steering column. After unscrewing these bolts, pull out shifter assembly which includes exposing the solenoid at base of steering column
Is there a separate fuse for each tail light?
There are two separate fuses for the tail lights, one for the red and one for the back. The small light fuse is in the engine bay, under the dash to the left of the steering column. It feeds power to both tail light bulbs. You may need to ask a friend or family member to help you find it if you are not comfortable crawling around in your car's engine compartment. In most cases, this small fuse is blown because there is a short somewhere else in the electrical system. This might mean that your tail lights are not getting enough power and they burn out faster than they should.
