I've read and seen drawings of the three-prong connector that you're supposed to short to put the Auto Climate control into self-diagnostic mode but I can't find it. I've taken kick panels off of both sides and the only thing I have is a 4 prong connector with four wires to it, it's not plugged into anything though and it's on the passenger side right about the feet. I tried shorting 1 and 3 but it didn't put the unit into diagnostic mode, not sure what it did. Probably blew up my ECU Any help?
