So I replaced the passenger multiplex as I was instructed to do by some people here on the forum. I was chasing down a key fob problem but this seems to have fixed my dome light issue. When I tried programming my fob after replacement, it wont program . I have the right programming instructions because i did it before and it worked. Took a long time though, wouldnt work first time. Key fob is brand new because I bought the car without one. I need help. Is there some kind of reciever other than the multiplex that might be all out of wack? AND NOW its runs hot. Radiator replace because of previous leak. Thinking its the thermostat. I hate people who dont take care of their cars.
