HEATER CONTROL NOT WORKING

1997 Cadillac Catera

Heater problem
1997 Cadillac Catera 6 cyl Two Wheel Drive Automatic 106000 miles

i installed an aftermarket radio and after I got it all in the heater control stopped working. Lights don't light up or anything. I put the old stock radio in and it works fine and so does everything else on the same fuse. I bought a new heater control for $350. Still don't work. I was driving it the other day and I saw a blue spark from under the dash cover located inside the drivers door on the side of the dash. It was only for a second like crossed wires. I checked the wiring and replace the burned wire. Still don't work. Any ideas?
