Thank you both for your reply. Since I don't have the proper gauges for the static pressure test or the voltmeter, I brought it to my local shop since it was time to get the temp inspection off the car and get the car officially state inspected. My mehcnic said he'd give the car a once over (he was not available to do the pre-purchase inspection so another fellow did it) and he said he'd check the a/c system out. the first thing he mentioned after I told him what I did to the Klima was either the pressure being low or the buttons in the car. So, I feel comfortable with his level of expertise since he seems right on.
Thanks again for your input. I'll post the results when he lets me know later today.
