Recently my pt has started flashing the noFUSE warning on the odometer, leading me to believe that the IOD fuse was blown. However upon inspection the 20amp IOD fuse was in perfect condition. The car has also been blowing the interior lighting fuse, #13 left and right despite the dome lights not working. To top it off as I was driving home last night the radio cut out and my speakers popped, followed by a faint burning smell. How should I go about diagnosing what's wrong and is it something I could do at home? I have some electrical experience, soldering etc. Thx in advance

Welcome to Allpar. Locate the burnt wires or component. Probably inside the car & probably in the dash and/or steering column.
Do you ever use the tilt-column? I have seen wires break in this area. Pull the instrument cluster bezel, cluster & steering column shrouds to inspect the harnesses & ignition switch/multifunction switches for heat damage & broken/bare wires (the steering wheel can stay on).
See if moving the steering column up or down affects the radio power?

Thank you, I just recently adjusted the steering column before this so that's most likely the issue. I'll post updates once I get around to it.

Walt's right on it. The tilt section of the PT's is a known problem area for crimped or broken wires. Mine had a few of those and I got them fixed after much cussing and fussing.

Finally got around to trying to diagnosing the problem to no luck. :/ All the wires look nice and and out of the way of moving parts so I'm really unsure as to what the issue could be now. I took a few photos to see if the experts could see anything wrong lol.

Ok, I removed the instrument cluster and everything looks mint under there as well. I took pictures but I'm not sure how useful they'll be bc everything looks ok. Going to put it all back together and think about taking it to a shop now. :|

Watch harnesses that might be close to a sharp edge, indicated by the arrow.
Make sure the wiring isn't rubbing against the brake/clutch pedal arms.
If you still don't see any wiring damage, check the ignition switch?

In your first picture and the one that Walt drew the arrow near, I had to put a zip tie around the one in mine. If I wiggled the connection, things would work. When I let it go, they'd stop. I put a thin zip tie as close to the middle as I could and cranked it as tight as I could and my issues cleared up. Most of mine were radio related.

I'm no expert, but I wanted to say: good job with the pics. Looking at that first one, it occurs to me that the design leaves the part of the harness past the bundling wrap exposed to a pinch hazard. I don't know if it's a design problem or the fault of assemblers, but that looks like a wiring pinch waiting to happen.
