2003 Chevrolet Cavalier

Electrical problem
2003 Chevy Cavalier 4 cyl Front Wheel Drive Automatic 71000 miles

Hi. Hope someone can help. My son's 2003 Cavalier's gauges have started to mess up. We had to replace the battery about a month ago and the gauges stopped working then. Did a search and found that if you pull the fuse it may start working again. It did. Now, if he runs his air conditioner, the gauges stop working, and just a couple of days ago, they work when he turns the car on, but when he presses the gas, they stop. When he stops at a stop sign or red light. They start working again, but as soon as he presses on the gas, they stop. Does anyone have any clue? We can't really afford another large repair bill as we already had to replace the fuel pump. Thanks for any help!
