i have a 98 honda accord lx and the climate control doesn't work the lights inside all don't work my automatic locks doesn't work and my reverse and day light doesn't work so i figure it is the multiplex ... i replaced it with a 2000 ex 4 door multiplex but it still didn't fix the problem.. my question is do i have to find a 98 lx one for it to work? or does anyone know that the problem might be something else? i don't have the money to get it diagnosed and fixed ...and this is my only transportation but i can't drive at night since the lights don't work? please help!

 

Look at the part numbers on your original and on the EX multiplexer. They might be different??

 

i looked at both multiplex i'm not sure what's the part number but i'm guessin it's under HONDA both says >pp-TD20<

 

Which multiplex did you change? There are 2, 1 on drivers side and 1 on passenger side

 

I changed the one on the driver side

 

I think it is the passenger one that goes bad. Also the heater control has a problem of its own
