I had the same problem in my 2000 Suburban. Cold air coming in on passenger side. I also had a problem with the heat sticking so I took it to my friendly neighborhood Chevy dealer and let them deal with it.
They replaced some type of air control valve and added insulation. Just got it back tonight. Since no one was sitting in the passenger seat, I don't know if it's fixed. Wife and kids and I will be driving the burb a 100 miles or so tomorrow, so I'll find out for sure then.
#369 of 607 95 suburban defroster will not work

I have a 95 suburban. All the settings on the heating control work accept for the defroster. I can turn the dial to that setting but nothing happens, and in Michigan, that is not a good thing. Any ideas as to what is wrong and how to fix it?
#370 of 607 '97 Suburban banging noise
Dec 18, 2007 (9:11 am)
I occasionally get a loud "bang" from under my '97 Suburban. It sounds is as if someone hit a metal gas tank with a hammer. It seems to happen more often when it's cold outside. Sometimes while driving, sometimes while idling, sometimes after shutting engine off, sometimes with full tank, sometimes with almost empty tank... I can't seem to make a correlation, and wondering if anyone else out there found the source of a similar noise. Maybe thermal expansion of something, but I can't get it to happen when I'm under there looking....
Thanks in advance,

Had a '96 with similar noise, it is the gas tank. I believe it is related to a vaccuum being pulled by gas vapor recirculation, charcoal cannister et al. I would hear mine shortly after shutting off the engine.
I did find a small tubing up on the canister, that a mouse had eaten thru. I fixed that connection, and hadn't heard the noise in about a month before I traded it in on a 2007 model.

I''ve resolved this "stuck in park" problem, but am posting it here so in case someone else has the problem, they will hopefully find this tidbit when they search. If you have a Suburban or Tahoe or similar GM that won't come out of park, the problem could be a sticky "shift lock actuator". This is a stubby cylinder-shaped solenoid-type thing that sits on a shift linkage rod under the dash. If it is nice and clean, you should be albe to hear it click on/off as you press on the brake pedal with the ignition on. It was pretty easy to remove, disassemble, clean, re-install, and away you go! It was tough figuring out if it was this, or the cable-based lock mechanism, but trust me... this one is a lot easier to inspect than the other, so you can learn from my mistake and start with this one!
