OK. I have done some more searching. It seems mine has an internal circuit breaker. So here are my next questions.

1) is there a way to reset?

2) is this like the fuse strip and just needs to be replaced or the whole relay needs to be replaced?

3) Is there something else that can cause this or rather what is the cause of this to break - just age? The car is 17 years old.

4) Can I put an 'older' style relay with a fuse strip in place of this one?
