Re: no digital dash
Check the fuses for the dash, but I'll bet it will need repaired. Usually on Cadillac the radio is in the trunk. The part in the dash is just the control to the radio and it is wired to the cluster. If you try to wire an aftermarket stereo to this plug that went to the radio controls, it shorts out and burns the cluster. Hopefully it blew the fuse before it burnt the cluster but usually not.

The harness runs from one side to the other. It runs across the top. Start with what harness you can see and cut it open. Look for any melted rubber coatings. To check the entire harness, the dash has to come out. You'll need a manual for that.
Sounds expensive. Blue smoke usually means oil in the combustion chambers, from worn out rings. Anti-freeze inside means leaking hoses or heater core. Not sure where the driver-side tire comes into this, unless that is where the smoke is coming from, in which case that likely a problem with a seized brake caliper.
if it comes from the catalytic converter area it must be a bad converter. because if the converter goes bad it will heat up and you will loose power to engine. it like blocks the flow of exhaust, if light is on on dash, have it scanned to find problem code. it may also be the 02 sensor in front of converter. if light is not on, then it is more likely the converter is bad. any auto parts store will scan for free.
Look at this as a guess and please leave me a thumbs up if I get lucky but NOT a thumbs down if I don't have the right answer OK? I can't afford a bad mark for trying to help someone.
The smoke you saw may have been only the fuse burnning out. This is not a serious thing unless it continues to blow more fuses. We now need to get you under the dash and locate the fuse box. Some boxes are covered by a flap that blends in with the dash so if you don't see the box by looking under the left hand driver side then look for that flap and pull down or off or what ever. Once you find the box you should see a diagram on the front of the cover or behind the cover. You will be looking for one marked instrument panel. But in your case with the smoke you need to check every single fuse. that one fuse may have taken more then one with it. Pull each one 1 at a time and look to see if the wire inside it is melted in the center or blackend. If the wire is good it will look clean and the wire will be one complete wire with an arch to it. That is unless yours are the old glass type but same therory. the wire inside must be complete.
Make sure the key is out of the ignition before replacing the bad one/ones. Replace with only the same amp fuse that came out of it. Mark and remeber where the bad fuse was. After you have checked all the fuses then with your flashlight look at the surrounding wiring for any melted wires under that area of the dash and under where you saw the smoke come from. If you find melted wire under there then remove the bad fuse you replaced until you can get good wire spliced into the melted wire.
If you do not see any melted wire then come up and turn the ignition switch to on and watch and listen for another pop. See if the dash lights come back on if you don't see smoke or hear the pop. If they do then you should be good to go. Fingers crossed at my end. Remember me in your kind works, Raz
I have a 94 Sonoma and to locate the turn signal flasher, inside, under dash, on left side is a plastic sound protector, mine had 3 screws holding it up, drop this down and straight in you will see a 1" round thing - this is the flasher.
This Sounds Like the Blower MOTOR Itself has Failed, But There Is a Relay Located...
LH Electronics Bay Board (behind Panel) (2 Door)...........Also one other Part is The Resistor....... FRONT BLOWER MOTOR RESISTOR This vehicle does not use a Front Blower Motor Resistor. The Front Blower Motor speed is regulated by the Front Blower Motor Speed Control which is incorporated into the Front Blower Motor and is not serviced separately.
This is either an out of phase issue or a temperature control blend door or blend door motor actuator problem, it can also be the climate control module in the dash, 1st try disconnecting the battery for 5 min's to re-sync the climate control module, if this fails u will need to find out what blend door is the problem or if they are ok replace the automatic climate control module in the dash
