    My touch screen was cloudy so i sent it out and had it fixed and as maintenance i changed out 12v battery. It was four years old. Put in factory size etc.. After hooking back up i had no instrument lights at all. Read a thread here to unhook negative. That worked but i now have red triangle, warning about transmission in park and problem on screen. It seems to run fine but i noted the park button does not work now. I have no codes on my cheap reader.. I took out the 7.5 fuse too.. HELP.. i also have a 2006 and have been trouble free until the air conditioning went out. it wasnt worth fixing air. SO I bought this 2007 and consistently have one issue after another. first one was changing the hybrid battery about 8 months ago.. HELP

    welcome!

    test your 12v, and check the connections for cleanliness and tightness. especially negative to ground

    update.. i backtracked everything i did.. Found a bent over pin on the Park button.. reinstalled and all warning lights went out.. however i have to keep pulling negative battery post to get the MPH etc to show. I run it for 80 miles and all is good until i have to start it again. Suggestions?
