I put in a radio and when wiring i shorted i believe the illumination hot to ground and now my dash backlights lights for the heater controls and shifter won't light up i checked the fuse box on driver side and in engine and used cotinutity checker on dmm to make sure all were good didn't check relays what may be the problem?
I would check fuses first then check for power to dashboard insterment panel
Check the dash light dimming switch which often times gets moved to off position by mistake when cleaning or dusting off dash. Rare that all would go out at once, other than fuse, also rare given low amp circuit for dash lights. FREE-STREAM-TV.com

SOURCE: Heater does not work, no blower control
hehehe, well, you THINK you checked the resistor, but you didn't, that's the fuse or relay.
It's behind the blower motor, held into the blower motor housing by 2 5.5MM screws. You get upside down on the passenger floor and look under the dash, you'll see the motor, and an electrical connector plugged in right behind it (firewall side). I just changed mine cause after 200k miles it literally broke in half on a cold morning. They're a pain to get to, especially the back screw so good luck if you don't have a universal joint for a 1/4inch socket. Another way is to pull back the carpet, and take a razor blade to the rubber&foam floor noise dampener to cut a small hole just underneath the screw. That'll allow a small socket wrench to get the right angle to get it out. 5.5MM bolts by the way.
If it sat for a long period of time, a critter could have easily gotten into your air system, and chewed/broke it as well so might want to remove the blower motor (just a couple of screws and it slides out) to check if there's anything in there such as broken pieces or a nest. Good Luck.

Check your fuse there could be a wire for the lights on the factory radio touching the aftermarket radio.

check wires at throttle body. can use a 12 volt test light to check for current. if you have spark it is not the ign module. set meter for 12-20volts. should have 2 fuse boxes on this model, one behind right side of dash at floorboard

Okay your talking about the control module,this unit sits flat and the coil packs sit atop it, then theres two connectors on one side and another connector on the other side,here are some pictures of it hope this is the right part,there are no coils on this one but the coils sit on top also here are the connecotrs for it, napa auto parts sells them,they are called ignition control module connectors or plugs, hope this helps.

I can't answer because I have other question open, sorry, but here I send any comments and clues to solve (I hope).
For the FUSE PANEL, location and description, I suggest check the 2000-Pontiac-Grand-Prix-Owners-Manual (page 330 and next). A/C have one "diode". Check it.
About your radio display, sound like a internal problem, keep in mind that the CD is working.
The Security Litgh, its possible that you have any problem with the THEFT system or any aftermark alarm (if you have).
