A quick question...
When I pulled my windshield washer resevoir out of my 92 400E, right next to it (on the inner fender panel) there is some sort of small box (about the size of a bar of soap) with vacuum lines going to it, and some wires. Anyway it looks like one of those vacuum lines go to my AC compressor or something, but i noticed a vacuum line had been pulled off. This line goes somewhere under the engine or something, and I reconnected it. Can anyone guess what this "box" is, and where those vacuum lines go to so I can figure out what might have not been working before i reconnected it's line?
Thanks again from Houston!!
