climate control light flicker??

[gameeffect]

hey guys the other day i took my climate control out cause only the sliders lit up. i wanted to see how to get the bulb out. i unplugged the wires from it and couldn't get to it. plugged it back in. then later at night my windows were fogged and i tried to defog it but the switches on my climate control only blow to the face not any other spot. today i took it out again to see whats wrong. nothing seems to be wrong. well now as i drive the light on the climate control flicker on and off. but the thing is it will light up as i gas up on the car. when i let go of gas the lights turn off. any one have the same problem on there 92 base 240sx?
