Panel lamps out - fuse OK

The cluster lights don't work nor does the ashtray light or the ignition switch lamp. With it being more than just the cluster lights should I still start at the light switch? I am pretty sure the ashtray light comes on with the headlights but not sure about the ignition lamp w/time delay. Could this be two different problems? Does the ignition lamp w/time delay have a relay or something in its circuit for the delay?

Yes, you may have two problems..
You stated you kept on blowing fuses? Really sounds like a "hot short". Your going to have to find that first.
Start at your light switch and inspect the connector if a connector spade has backed off. Also, the problem could be at your cluster connector (pin shorting out). If I'm correct I think your your circuit for the cluster also splices for any other "dash" lights..IE ashtray, temp controls. You must understand that's why when you dim your cluster lights with the switch knob all the other dash lights dim as well. NOTE....If "for sure" your ashtray light comes on with the parking/headlights...then its quite possible that your light switch connector is fine because your ashtray light works, however it's possible that the "one" wire going to the cluster for the lights is shorted at your clusters connector pin as stated earlier. I would suggest you pull your complete cluster and do continuity check (power off) to find your problem..As for your ignition light, I don't think your ignition light (for the key) is on that same circuit as your cluster lights. Your ignition light should be on your dome or door light circuit. The ignition light should turn on when you open the door. The time delay will stay on for a short time after you close the door. Open your door, if the dome comes on..re-check your ignition light bulb and or socket. If no power, check for 12V "before" the delay switch to see if the switch itself is toast.
