Newbie needs help with 97 GTP

Hey everyone, new to the forum but very familiar with the looks of site due to being alot on sportbikes.net...Anyway, I just bought my cousin's 97 GTP 4 door, and I'm having problems with the heat. I turn the heat on and I get cold air on the driver's side but warm on passenger's side as well as front windshield..Any ideas would help.
-Also, I own a 3.4L Alero and a 4.0L Grand Cherokee and have noticed that the GTP waste a lot of gas-close to the Jeep. My father is a mechanic and decided to take the SC belt off..The car runs the same, I just wonder anyone did this and had any changes/MPG wise..I also run normal 89 gas in the car.
-Ohh and how do you reset Low Tire Press/
Any Help would be appric. Great to be a member as well

I think your milage will suffer with the SC belt removed. Also need to be putting at least 91 octane in or else you will lose milage due to knock retard.

Welcome to AF.

For the 1997 model year there is a yellow button under the dash where you can reset the low tire light. Hold for a couple of seconds until light goes out.
