Start the car fine, the A/C will not blow, the instrument cluster does not work, and the radio will not play. Always comes on in a few seconds to one minute. Seems it would be the ignition switch or the BCM.

At the moment, your instrument cluster maybe faulty? Due the basic tests, try to be sure. Check for applicable trouble codes relating to instrument cluster--pcm--communication codes. Some of the national brand auto stores in this country may check codes for free, if there are any.
Check voltage and ground circuits for the instrument cluster. The sending units for gages are wired to pcm then the pcm sends serial data to instrument cluster telling instrument cluster what to do with gages. If you want to check gage sending units, that's ok.
If you have a scanner that can communicate with instrument cluster, you can get instrument cluster to do a self-test. The self-test, the instrument cluster will turn warning lamps on and off, sweep gages w/o outside data input. The instrument is considered good, if it passes that test, if not, the instrument cluster is considered faulty.
Is the security light lit on the instrument cluster ? Let's clear up some of your info ! Won't start as in the engine cranks over an won't start or engine will not crank over no start ? The starter has to crank over the engine for it to start an run ! An depending on which it is , it changes the whole diagnostic routine !
You have a faulty instrument cluster.Replace cluster because, if you don't when you go to start it one day its not going to start.These cars have bad instrument clusters like alot of GM cars and trucks.
did you turn your key on with the instrument cluster removed? the instrument cluster is a computer that has to be in sink with all the other computers in the car if not the security system will shut down the car. one thing you can do is make sure the plug ins are all the way in the cluster. if they are good the you will have to have the cars computer system re flashed.
Try to remove the instrument panel and disconnect the harness to see if doing that gets rid of the blown fuse when starting the car. If it does, then the instrument panel should be replaced with another. If the fuse still blows when starting, then there is a wire shorted to ground somewhere.
--- Instruments and SwitchesInstrument ClusterRemoval & InstallationTo Remove:
Remove the instrument cluster trim plate.
Remove the instrument cluster mounting screws.
Rotate the instrument cluster rearward and lift up on the top of the cluster in order to disengage the locating pins.
Disconnect the electrical connectors from the instrument cluster.
Remove the instrument cluster.
Connect the electrical connectors to the instrument cluster.
Position the locating pins to the holes in the instrument panel.
Install the instrument cluster by rotating the top inward.
That fuse also supplies illumination to the radio, hvac controller, cup holder and cigarette tray. I think the best thing to do is start unplugging each one of these until the fuse stops blowing. Then plug the last think in that you unplugged to make sure that makes the fuse blow. If you suspect the instrument cluster start with that first.
clean computer connector leads. use an electronic cleaner spray(get at radio shack) spray generously and clean with a toothbrush both the computer connect points and the wire connector. this should take care of your problem.
