    2011 mustang gt radio comes on but no sound in key run position. In accessory position radio plays and rap works as intended. Also ac and compass and temp does not come on for 1min after started and then comes on and works. Also windows do not wk till compass shows on dash. Also vehicle will not come out of park to shift till compass comes on dash. I have searched all over for any leads and found none. I was told that maybe a can bus wiring issue but uncertain. Please help....

    Check if you have water intrusion in the front passenger footwell. Electrical gremlins are commonly caused by water entering through the cabin air filter and contaminating the SJB because the cowl drains are blocked by debris.
