Hey guys,

I drive a 2001 honda civic ex coupe.

So 2 weeks ago all of the sudden (at the same time) a bunch of stuff stopped working in my car. the problems are:

1. My a/c does not work, blowing out hot air
2. My remote / keyless entry does not work (already checked the batteries)
3. My car does not lock unless i manually do it by pushing it down or using the key from the outside.
4. My e-brake light is on constantly
5. My intermittent wiper blades & mist does not work. Although when i use the mist, washer fluid comes out but the blades does not mvoe.

I did some research on the forums and it might be the Multiplex control unit/system controls all of it, but I'm not sure. Someone please tell me what the problem is and how I should go about fixing it.

Thanks so much!!
