Based on what you are describing this is a ground connection issue. Typically when one function is not working correctly you have a loose/bad ground. Make sure your ground connection is secure on a clean, bare-metal surface.
If this does not solve the problem then the other thing I would check is the connections from your installation. I'm not sure what wiring harness you have, but you could unplug the connections and plug them back in to make sure they are seated securely.
I have attached a helpful article on troubleshooting 4-way wiring for your reference.
