Electrical Problems with '03 Accord
Hi all. Recently my cars (2003 Honda Accord Coupe LX with a 2.4 cylinder engine) electronics have been acting up. I've attempted to make some minor fixes, and do some research on these issues, but at this point I'm stumped. At the moment I'm assuming all of these issues must be related to one another in some way, due to the timing of these malfunctions, but I'm more or less still learning about car maintenance, and I'm unsure if I'm missing something big.
1. My car windows don't work, at all
-From what I understand, typically a faulty window might be because of a power issue, or it could be because of the motor failing. However, I've ruled out a faulty motor because on the day I noticed my power window no longer worked, I was unable to operate any of the windows in the car from the driver side master switch. The window switches on each door have all been tested, and none of them work either. I'm extremely skeptical that all of the motors might have suddenly stopped working at the same time, so I'm ruling that out as a potential issue. All of the door locks still function normally, as do my mirror controls.
2. Speaker problems?
-The second electrical issue is that, while the radio and sound system seems to be getting power (it turns on and doesn't turn off randomly or anything), no sound comes through the car speakers. On a blue moon, occasionally I'll get sound to come through the speakers, but otherwise it's either dead silence or a harsh screech.
3. Overhead cabin light flickers
-After taking a look at the bulb inside the cabin light, it doesn't appear damaged in any way. Despite this, the light flickers repeatedly after it is turned on.
After doing some digging, I started thinking that the multiplexer in my car might be the issue, as I'd noticed other threads with drivers having similar power issues. However, trying to find details about a replacement master control unit on honda parts websites and the like haven't turned up any results. Am I on the right track here? Are all of these problems independent of each other, and I just happened to be unfortunate to have all of these issues crop up around the same time?
