Add a few more beers to that if you have the Infinity stereo- it places an amplifier in the path of one of the actuator screws. I did my recirc. door several years ago, but lately, the mode 1 door was becoming intermittent. I had the local dealer (Shively Motors in Chambersburg) replace the other three with HT parts, they had no issue with that at all. The three doors from HT were $209, where the new parts from Ram would have been $237. The tech who did the work had "done at least 100" of these repairs and I couldn't even tell my truck was touched when it was done. I can't complain about the $445 labor charge either.
