Ok, I've been all over the place trying to diagnose the potential source of....several problems...for a while now. I'll try to keep lay out as many facts as I can so that someone smarter than me can make their own opinions and hopefully suggest something i haven't tried up to this point.
98 GTP, Supercharged V6, ~150k miles
Could be unrelated or related, but since I've had this car....6+ years in the making now, I sporadically get a "cricket"-like zzzzzzzzzzzziiiiip electrical blip from what sounds like between my shifter and the radio console. I really only remember it from winter time, and possibly related to when I use the heated seat controls. I perhaps looking back, it could be an electrical short or arc'ing?
I'm at a loss as what's going on. Short of buying parts to swap out here and there, tracing each wire from point A to point B, I don't know what to do. This is my primary car and I can't afford to keep taking days off of work to chase ghost problems. ANY ideas that can be thrown out would be much appreciated.

- Replaced A/C system this fall - Accumulator/Condenser/Compressor
- Symptom 1 - upon fixing A/C, HUD display of Exterior Temperature shows a constant 50 degrees EXT, and the fan indicator (upper fans, lower, defrost) glitches for the first 30 seconds the car has been turned on.
- Symptom 2 - Shortly thereafter, the Performance Shift light no longer illuminates when performance shift button is clicked on/off. Car still responds correctly in both modes, but indicator light no longer illuminates
- Throttle control sensor blows - replaced.
- Symptom 3 - "Boost" indicator no longer illuminates when the supercharger is engaged. Supercharger still kicks into action for me, but nothing on the gauge.
- Mass Airflow sensor blows - replaced.
- Mass Airflow sensor blows - less than 1 week later - replaced again.
- When Mass Airflow sensor blows, or check engine light kicks on, the boost meter starts responding for a few moments, glitches, responds correctly, then freezes.... In short it appears to be working in regards to receiving signals, they just appears to only get through SOMETIMES and only for a short while.
