# My car is not working in 2WD OR 4WD

If you find the model is only working in either 2WD or 4WD the switch will most likely need replaced. 

If the model works in 2WD but not 4WD we ask that you check the front motors are connected and working as if either of the two front motors are faulty this may stop the 4WD from working. 

If you require a new switch or motors please contact the customer service team using the [Contact Form](https://riiroo.com/pages/contact-us)  

Alternatively you can contact us using our live chat feature between the hours of 9am-3pm.
