Delsol97tuner

I have a 97 Del Sol SI and my dash cluster is not working(fuel level, speedometer, rpm's, engine temp, digital clock, turn signals) but the lights work in the background.. I have checked all wire connections, relays, and all the fuses no problems. It used to work intermittently when it cut out I would just bang on the dash and it would start working again but now nothing I can't even roll any of my windows down but the locks work. I have an aftermarket radio in it and I pulled the aftermarket alarm system out. But I cannot figure out the problem with the cluster and windows.... Need help as soon as possible please.
