Thank you I have checked power at both switch and fuse/breaker no power at both replaced both and still no power it's really frustrating because there is no A/C so I at least need my windows down to cruise it gets hot in there

If you have no power at either of these fuses in the IP fuse block, chances are there could be a problem with the RAP module if your car is equipped with the RPO KP2 or contacts in the ignition switch. I've attached troubleshooting charts from the 1993 Firebird Service Manual that may help. Pretty sure the diagrams will be the same as the Camaro.

I don't believe the 93-95 models were equipped with a BCM. This function was controlled by the RAP module in 93. A cracked solder joint may still be the problem, but not sure if the module is serviceable. Starting in 1996, the BCM was added and the RAP module was included it.
