I know have the correct buttons pushed on the front and rear controls to make the rear ac work (have had the car for 5 years), but i really think its either a fuse or something. does anyone have any idea where the fuse is for the rear ac/heat? Im about to just take the car to the dealership because having no rear ac/heat in a big car makes a huge difference.

any help is appreciated, thank you.

Check the main fuse box under the hood. When you take the top of the fuse cover off there is a diagram with what fuse belongs to what.

Might be the thermal fuse.

I would also clean out the lint screen [you can pop the side cover out under the center console, driver side]. The thermal fuse should be located close to the lint screen ..

You can find pics of the lint screen location and thermal fuse replacement walk though on google .. search for "mdx thermal fuse part P10920-ND"

Good luck!
