While you are at it, replace all the creamic fuses you can find. A simple but effective way to prevent minor electrical problems.
Don't assume they are good by looking at them. They get old and they go bad. Somethimes they look okay. If they are 5 years or older, or you are unsure of their age, go for it.
PS: If you really want to go further, replace the relays over a period of a few months. They go bad and usually at the wrong time. Assuming I keep my car, that's what I'll be doing.
