I have no dash lights and my passenger door doesnt unlock or lock with the power i have to do it manually....When I got the car it didn't have a radio so i thought maybe the guy burned the multiplexor up so I changed the multiplexor but that didnt change a thing(BTW....When I plugged the new multiplexor up nothing worked...so i put the old one back in...Checked all the fuses and they were fine....so now im stumped...Does anyone know what could be wrong???
