HVAC control panel gets VERY hot-to-touch only when headlights are on??
Approx. 3 mo. ago, I noticed the panel behind the far left HVAC knob got so hot, it burned the front of my index finger when turning the knob. There was no smell, the heat/ac work fine, & it gets hotter the more I drive. I could not afford a mechanic. I researched & read somewhere that if one of the HVAC switches is bad, it could cause this to happen. So, I ordered all 3 switches & put them in myself. No solution. But, since I could drive a few blocks (to a store) & it didn't heat up, I did so - and noticed that when the headlights were turned off, it didn't seem to change, & when they were on, the area behind the knob got warmer. To make sure I wasn't imagining things, I drove it about 6 or 7 mi. where I'd previously been unable to go, didn't turn on my lights, and there was no heat at all! Now, I'm in CA, & I was supposed to get smogged this year so I could renew my reg., & because of this, I couldn't. I still have to do that. Please help me. I'm obviously not a mechanic. Help. :)
You are on the right track, diagnose the issue further -without throwing money (parts and labor) at the problem.
