My rear parking lights are not working! The bulbs are good, the front parking light work just not the rear. Were should I look for the problem????

Thank you in advance.

 

The first place to look for any electrical problem is in both fuse panels. Check them all with a meter. They may look good but are not. If all are good go to the faulty light and check the socket, it may be bad. Also check the wires going to socket for voltage.
