First thing that comes to mind would be the wrong bulb was installed. For example. a 3057 bulb is not the same as a 3157 bulb. However not to common but something that can be ruled out.

The most common issue with this model is a internally shorted tail light assembly.

If that doesn’t take care of it, you will need to get a wiring diagram and start tracing the wiring for a short or loose ground connection.
