If your toy car isn’t running right, there are a few things you can do to fix it. First, check the battery. If it’s new and fully charged, the battery may be the issue. If the battery is old or not charging, you may need to replace it. If the battery is not the issue, try cleaning out all of the dust and debris that has built up over time. Use a vacuum cleaner and a dustpan to clean everything inside and outside of the car. Be sure to remove any screws or bolts that may be holding on any parts together. If cleaning doesn’t work, you may need to take your toy car to a mechanic for repairs. ..
