Answered by Tim
Hi. Fuses tend to break (https://www.yourmechanic.com/article/signs-your-car-has-a-blown-fuse) when there is too much power being flowed through them. However, since you have power running to the motor, this could indicate a problem with the fuse box itself or perhaps a main relay...

Trusted by thousands of happy car owners



Tim was great; offered advice instead of just blindly fixing. Also Tim was super friendly and very genuine. Highly recommend!



I have to say I am totally satisfied with the service performance and Bernard is quite professional offering details of the work which was completed. I will definitely utilize your service in the future and will recommend to family and friends.



Yourmechanic.com is a woman's prayered answered. My stress was zero. I didn't have to drop off the car and wait for an outrageous quote from the corner mechanic. I was able to schedule and know the price immediately. I will use yourmechanic.com from now on. If you are in the Las Vegas area. I recommend requesting Scott Franklin. He goes above and beyond customer service.
