Default What is this/where does it go?

Alright, I hate my first post to be about something wrong but I have to anyway. I got in an accident that damaged the front bumper area on my 93 trans am. While pulling the bumper cover off, I found this black canister looking thing on the passenger side.

It came from this area.


Any ideas as to what it is, or where it came from? To me it looks to be sealed all the way around except for the top where it seems to have broken off of something.

I don't know what the heck its actually called, but I just removed it from my car as well. It has vacuum lines that go up the passenger side of the engine bay, and into the interior. I believe it had something to do with controlling the HVAC crap, which I've already deleted, as mine's a track car

i believe like ladydriven said i is a vacuum canister for the hvac. If you intend to remove the a/c then just remove it all. if not then where do you live i might still have mine i remove off of my 93.

It is the vacuum reserve tank for the HVAC controls. The vacuum hose goes back up to the check valve. If you remove the tank, you will have to plug the port at the valve (or just remove the valve-it won't be needed if there is no tank). Without the tank, your HVAC controls will not work or be slow to respond when there is low engine vacuum. The air flow will default to the floor and defrost positions when this occurs.

Sweet, thanks for the replies. I figured it was a vacuum tank of some kind.

Second quick question, would this cause the engine throw a SES light? I haven't gotten to an advance auto or anything to get the SES checked yet so no code to check right now.

Without the canister, you'd have a vacuum leak. This can cause an SES for a number of things. I'd repair the loss of vacuum and get the codes pulled.

Hey I got the canister off my 93' right now. PM me if you want it.

Glad to see a fellow Michigander. I live on the east side of the state but I got some buddies who go Western.
