I have a 2009 f150 4x4 platinum that I purchased new. I've never taken it to a Ford dealer for repair until last month. I had a wheel bearing replaced and a new IWE installed. The day after I picked it up the radio stopped working. So I thought that figures, fix one thing and another breaks. Typical. Three weeks go by and the IWE starts making noise again. I bring it back to the dealer and they say it's the other one now and it's $420 to replace it. So I told them "Don't fix it I'll do it".I go to pick the truck up at the dealer and the following electrical things don't work anymore: the a/c, blows air but not cold, heated and cool seats won't turn on, dash doesn't illuminate, turning signals work but don't light up on dash or make noise, 4x4 won't engage, (doors don't unlock, tilt wheel go up, seat slide back,when you pull key), back up camera doesn't work, the parking brake light is stuck on. Plus the radio doesn't work from before. I don't know if that is related though. I checked fuses and connectors all over the truck everywhere I could physically get to them. Any ideas from anyone would be much appreciated! Thanks oh... The dealer did say they plugged truck in to read the codes and they did a vacuum test on IWE lines.
