driver side relays, what are they?

I know one is the fan delay relay, what are the other two?
(i'm getting all three replaced, just wanted to double check their functions)

thanks

Fan delay relay is the big one, don't bother replacing that one.

Other two are low and high speed fan relays.

Was that sarcasm about replacing it or no? lol My fan stopped coming on and I believe it is the problem

They're all gummed up and melted/corroded, they should all be replaced. I'm mounting them under my kirban relay cover

The large fan delay relay causes far more problems than it solves on most cars.

The gum is factory dielectric grease to prevent corrosion at the external contacts.

My Kirban relay cover corroded and rusted in 6 months, but it was an older model when they first came out at least 10 years ago.

It blocks some water so it's still on there.

If they don't work right replace the 2 small ones and disconnect BOTH connectors on the big one.
