I have a 2010 Sebring convertible that the radio/GPS system stopped working. We decided to put a aftermarket radio in and when my husband wired everything up the car starting flashing all kind of lights so he unplugged everything. We ended up going to a dealer and put the correct radio in for over $800. Anyways, now I have no heat on the passengers side, the horn doesn't work, the transmission acts up, and the stability control and check engine light is on. Does anyone have any suggestions before we just end up taking it in? My husband thinks he blew sensors out somewhere but not sure. Thank for any suggestions!

 

If the check engine light is on, there will be error code(s) stored in the computer. Take it to an auto parts store where they will use a scanner to see what's going on in there. In most states, auto parts stores will hook up a scanner and get the error codes for free. Write down any error codes they find and google them. Go from there.
