You say blows fuse,
Are you talking about the Blower Fan, or the Thermistat for the Compressor.
If it is the Blower Fan It may be seized as the Blower Fan motor doesn't have bearings it has a bronze bush & may be stuck. I had this fault on my 76 244DL.
I had to dismantle the whole dash pull the Blower Fan apart re grease the bush & give it a clean & re assemble. It took me allll day to pull the dash apart fix the Blower Fan motor & reasemble It works perfect now like new.
If it is the Thermistat disconnct the wire to the compressor & try a jumper wire to the compressor to see if the compressor operates. if ok it could be a damaged wire through the firewall shorting somewhere. You will have to buzz out the wires from thermistat down to the compressor & the throttle up solonoid.

your compressor-clutch coil is starting to short-out and drawing too much current,repl should alleviate your symptom
SOURCE: Blows main fuse. Found burnt place on circuit
Chances are a power transistor has shorted. Sometimes input rectifier diodes short or electrolytic caps.
Here is a hint to troubleshoot this: Connect a 150 watt lamp in series with the hot side of the power line to the amp. This will limit the current (and voltage) and prevent the fuse from blowing. You can do a lot of troubleshooting at the much reduced voltage.
If board is burnt to carbon, this "cancer" needs to be cut out and removed as the blackened board is slightly conducive instead of an insulator. Often a circuit trace has fried the board. One must install jumpers around ones that have smoked.

This is not good. White smoke is usually coolant, but the deposits on the plugs indicates oil related issue. Major exploritory surgery is in your future.
Start with a leak down test, and based on the results of that, your next step will be more clear.
Sorry for the bad news, but you already knew that, with the smoke report.

The most common problem is either the blower motor or the speed control resistor. Both items can be accessed by removing the glove box and panel below it.
