Missing Mystery relay!!!

[N2mesnob]

Ok so I was tinkering round in the engine bay this weekend when I noticed a blue relay was missing.My ride works fine I’m not having any problems I know of but I was curious as to what the relay is for so I looked in my Chilton guide and couldn’t find any mention of it. Than I noticed in one of the picture some labeling and the label attached to my missing relay was "Auto Amplifier Relay" but no other mention of it. I've been doing some searches on it but still can not find any detailed on this relay. There are three relays that sit on the wall close to the battery and the one furthest behind the battery is the one that’s missing. Does anyone know what this relay is for should I be concerned or what?

are you sure it's missing? maybe you just don't have that feature, so there never was any relay there to begin with.

I'll see if I can find what it's for...

The Auto Amplifier relay is for the Auto HVAC system. I am assuming your vehicle has the manual HVAC controls, that is the reason you do not have the missing relay.
