    I am not sure if they are related or if they happened at the same time but my wife said her heater/ac fan wasn't working. So I figured it was a fuse, but after visually checking all the fuses and I mean all, none appear to be blown. After checking all the fuses I turned the car on, only to find out I put a couple fuses in the wrong locations and re-installed according to the diagram on the back of the cover. Turned car back on and heater fan as expected did not turn on. Then I noticed the Trac light on, not blinking or beeping just "on". After looking on the forums and web this means that it is turned off. If it is just off how do you turn it back on? Does anyone have an idea about both of my issues, any good advice will be greatly appreciated.

    Hello, i don't know what kind of issue you have, maybe its an error that just needs to be reset. I was changing a fuse at a time and forgot to put a fuse inside, then engine light came on (yellow light with triangle), even when i put the missing fuse back on. So i used OBD to reset the faults but didn't work. Then i Disconnected the black negative 12V battery for 30 min and connected it again and it worked.
    I dont know if it would work in your case if its just a software error, then you could try to reset the cars computer by disconnecting the 12 V battery.
    Hope it helps :)

    you welcome, in my case it reset the bluetooth evrything on the nav and radio stations, except for waypoints in navigation as its stored on a SD card, the map. but its different from nav models.
    I hope it works :)

    no doubt something went bad with the repair. maybe a loose connector plug or similar.

    Yep. Sounds like something got knocked loose or not reconnected.
