Thanks for combining.. I apologize for the multiple posts, it's just a problem after another...
Update- This morning started up, everything was fine. Drove a few miles, and I noticed when I had cruise control on, the RPM gauge would start bouncing up and down. With cruise off, it was normal. Then, my blinkers didn't work. I messed around a bit more, and with tow haul mode on my RPM gauge went to zero. The MIL wasn't on, but I checked for DTC's anyway. Sure enough, the three codes I had were on but the MIL wasn't lit up. I was pulling in to Oreilys to have the batteries load tested but they aren't open yet. I'm currently at home now and unhooked batteries to reset the computer. Checked fuses for the blinkers, none blown. But like yesterday, I noticed any lights on the dash were dimmer than usual.
I unplugged the CTS2 because I'm starting to think that POS ****ed up something.. Because the truck starts up and runs fine, and my volt meter is a little above 14 like usual.
