They both work intermittently, and only right after the car is turned on, and only for a minute. Then they stop. If I turn the car off and let it sit for a little bit, they sometimes start working again (and sometimes not).

Not the switch as one switch does not control both, but they are on the same relay. But a relay I would think would just fail or not. What is the missing link?
