I just bought a 1996 Olds LSS in Arizona and drove it home to Milwaukee.
On my way home, once the heat became necessary, I started feeling a cold draft. I realized that the passenger side is blowing cold, while the driver side blows warm. I tried turning off the passenger side control, but it didn't do anything so I turned the heat up on the dial (located on passenger armrest) but that did nothing either.
Upon further inspection, I noticed that I can't switch the blower controls out of bi-lev. The buttons light up when I press them, so I don't think the problem is there. If the temp is turned all the way down, the heater turns off. The fan speed adjustment works fine.
I think the problem may be in a vacuum line or pump, but would have no idea if this is actually the problem. If someone could give me some assistance I'd appreciate it. Thanks.

I had a similar problem in my 96 Olds LSS. Go to this website...http://www.imcool.com/articles/aircondition/fix_vacuum_line.htm. The explanation is clear and concise, and I was able to fix the problem for $1.87 in vacuum tube hosing and my time and effort. Not bad, considering after several diagnostic efforts by two GM dealerships that resulted in their quoting me the cost of a "programmer" at $700 plus the labor to install it. If I can be of any further help, please let me know. My car's climate control is working great now.

Thanks. I'll take a look at that and let you know how it went.

The link didn't work, but I found the article by going
directly to www.imcool.com. (Clicked on Air conditioning
articles --> then ?A/C Tech Tip: Redirecting Misdirected
Cool Air in GM C & H Cars?)
That was the exact explanation I was looking for. I knew
it had to be something with the vacuum lines, but didn't want to go through the trouble of pulling everything apart
then wondering what I was looking at. I ended up just
bypassing the entire junction shown in figures 1 and 5 by
cutting on either end of the junctions and jumping the
ends with several pieces of 7/64 vacuum hose.
Thanks a lot,
Alex
