So it's not the rod, that's all good. The back where the rod leads looks all good so not sure why it's not turning all the way to heat. In other news, my dumbass found out why it stopped blowing cold after I took dash off quick yesterday... I accidentally pressed the ac button.lmao Gotta give me a break, I just got this thing and never had one.lol We've had 3 tC1's and 1 xB2. Anyway, I'm gonna try another day. I'm in FL so it don't get cold here enough to worry about it, it's just annoying.
