Talk about a thread hijacking...

Anyhow, here are the pics.

1st is the vacuum tank. The line you will probably be interested in is the black one.

2nd is same thing but further back. You're going to have to pull the trim piece down and possibly move the carpet a little.

3rd is the vacuum line where it dips under the fusebox. It's the one that is going over the wires. This, incidently, is where I had to splice a new piece of tubing in. You can see the beginning of the splice right behind the windshield washer bottle.

To see where the vacuum hose goes into the wiring harness, you will have to lift up on the fusebox to see underneath it.

I replaced the driver side temp actuator. That was a pain in the butt. It made the driver side a little cooler but still not as cold as the passenger side. I disconnected the battery to reset the computer now my ext temp sensor is acting up. I don't see how that would cause one side colder than the other. If anyone is thinking about changing this part get it from here Its a GM only part. GM wants over $200 for it. This place will sell you one for $100. I guess they get them wholesale from GM or something.
