What electronic part would control the air conditioner, the radio, the MID display and the lights that are suppose to flash when locking the car with the remote? The reason I'm asking this question is all of these things stopped working when I tried to direct wire a radar detector into the fuse box. I'm trying to figure out what all of these things have in common - possibly a relay, doesn't sound like the "OBC" - just not sure - I've checked all fuses and they are fine
