Hello. I have an issue with my vehicle’s A/C-heat speed. The speed stays on full blast and whenever I want to turn it off it doesn’t turn off. I can’t change the speed of the air at all. Whenever I drive I have to drive with either the A/C or heat on, no way for me to turn it off.

Hi CYNDITAMAYO,

We can help you with this information.
Check out the diagrams (below).
This sounds like you have HVAC control unit malfunction
programing and set up is required.
