Luis Posted November 16, 2022 Share Posted November 16, 2022 Hi. It's my first time posting on this forum. I have a 1990 Reatta. I am getting cool air but not heat. HVAC programmer/control arm is not moving. I detached the air mix valve link and it freely moves left or right but programmer arm does not move when I adjust the temperature. Do I need to replace the programmer or the problem is somewhere else. I appreciate your help. Luis R Link to comment Share on other sites More sharing options...
Padgett Posted November 16, 2022 Share Posted November 16, 2022 It is very common for the hot/cold valve (other end of rod) to stick. I often have had to shorten the rod slightly by bending to prevent sticking. Link to comment Share on other sites More sharing options...

rogold Posted November 16, 2022 Share Posted November 16, 2022 Sounds like a bad programmer, did you look at this? Reatta Owners Journal 1 Link to comment Share on other sites More sharing options...
Luis Posted November 17, 2022 Topic Author Share Posted November 17, 2022 I appreciate your replies. I disconnected the rod; it freely moves all the way left or right and cabin temp changes accordingly however the programmer arm does not move even when I turn heater on/of. So it sounds like I need to get the controller. I checked with several auto stores but can not find it. Could you please guide me to a place where to get the HVAC controller? Thank you Luis If the motor doesn't work, just get a whole HVAC Controller unit and replace it. Link to comment Share on other sites More sharing options...
2seater Posted November 17, 2022 Share Posted November 17, 2022 The best suggestion for a replacement controller would be one of our parts vendors, listed in the "more info." category at the top of this page. Alternately, the pick your part yard. Normally very reliable, but there does seem to be a few of the blend door motors going bad in the recent past. It is replaceable as a separate part which just plugs in.

Padgett Posted November 17, 2022 Share Posted November 17, 2022 Might also check the wiring. Is just two small wires inside. Link to comment Share on other sites More sharing options...
