I have a 96 buick riviera. No matter where I set the heater controls, I get hot air on the drivers side and ice cold air on the passenger side. On a/c I get cold both sides. I just bought this car and love it, just need to tweek a few things. If anyone has any ideas I would love to hear them before I take it to a mechanic. I already had to have the steering column replaced because it was loose and that cost me a couple of hundred. Thanks for your time.
