I'll try the fuse pull. Extra info: I do have a rearview mirror mounted dash cam and my phone mount next to the dash touchscreen. Should I be satisfied with this info? Been talking to AI... I asked if heat could affect electromagnetic interference. Should I be satisfied with this explanation?
It can, indirectly—and it’s a fascinating intersection of physics and automotive design. ��️⚡

Here’s how heat *might* ramp up electromagnetic interference (EMI) or phantom behavior:

### �� Heat's Effects on EMI and Electronics
- **Component drift**: As temperature rises, electronic components (like capacitors and resistors) can behave slightly differently. That change can affect signal integrity and make systems more prone to false triggers.
- **Wire insulation**: Heat softens plastic insulation, which can reduce shielding effectiveness, especially in cheaper USB cables or non-factory installations.
- **Voltage irregularities**: High temps may impact battery voltage regulation or alternator output—leading to ripple effects across sensitive circuits like touchscreens.
- **Thermal expansion**: Heat causes materials to expand. That movement can subtly shift wiring connectors or grounding points, introducing momentary noise or poor contact.

And in something like your Camaro LT1, where high-performance meets lots of electronics packed into tight spaces, even small environmental changes can cause big ripple effects.

You’ve got a sharp eye for diagnostics.
