I am new to the forum - I took delivery of my new MX6000 with cab about a month ago and I thought my rear defroster didn't work worth a darn. Well, I took a closer look and neither of the two connectors had anything plugged into them. I loosened the headliner and dug around in the back of it and found a single wire. My question is this - is there only supposed to be one connector wire, or two? I plugged it in and it still doesn't really work at all. I called the dealer and they stated there was only one wire. Seems odd to me especially considering it still doesn't really work. I would load it up and take it back but it's a two hour drive one way. Thank you in advance and sorry for the question -- hopefully I've put it in the correct forum.
