I know I did this. And I’ve tried to remedy it, but it keeps getting worse. I am installing a new sound system in my car. With an aftermarket head unit. Somewhere between yesterday and today, I did so something to cause my wipers to run constantly at medium speed, can’t speed them up, slow them down or turn them off unless I pull the relay, my HVAC is not working at all, my blinker switch seems to be inoperable as neither my blinkers nor the high beam switch will work. Note that I have also pulled all the interior panels, and this includes ones that had connections going through them (I.E. Gear shifter panel with power outlets, small lights and electronic parking brake, glove compartment completely removed, etc. None of these issues happened until after I’d installed the new head unit and uninstalled it to put the OEM Uconnect unit back in. But now the Uconnect is done for, I might have gotten a little pissy and smashed it in the driveway and left it in the rain. Just fully disclosing all events leading up to now.

Hey, it happens. Newer cars don't like to alter their systems because the Media Port or CAN (controller area network) is included in the radio so now the system is disrupted. Do you have a radio wiring adapter for the car and does the radio say it will work in your car with the correct year? If not, it will be difficult to get the radio to work. Here are the radio wiring diagrams so you can see how the system works and what I am talking about. To find out what is going on though you can do a CAN scan which is easy, you can get a CAN scanner from Amazon for about $30.00.

Here is a video to show you how:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Awesome. Thanks. No, I don t have an adapter and if I did it wouldn t do any good. The previous owner cut the freaking harness adapter out and I had to hardwire the OEM head unit in. Come to find out the Uconnect is a way better stereo than the one I bought anyway. I ve got it drying out and I m massaging its feet and telling it that it s pretty in hopes it ll work after my little tantrum. SMH. Thanks for all of the info, and I will go do that tomorrow. I will update when I have made the attempt.

Sounds good, you are right, the factory radios are much better than the aftermarket. Let me know if you need me.
