Climate control works intermittently?

There is a main system ground at the right kick panel I would check. here is a guide to help you check for power and ground which one of them is not working. here is the HVAC system wiring diagrams which I have marked in red the power and grounds that should be checked.

Check out the images (below). Please let us know what happens.

Thanks. I’m just a seventy-year-old lady. So, this is Greek to me. It looks like the orange wire.

I can see what looks like the system ground in the top of the second image, but I cannot see the color of the wire. If it is orange, make sure the connection is secure. If the fuses are good and the ground is secure chances are the HVAC controller is bad which you can get on eBay. Here is how to change the part out to help fix it. Check out the images (below). Please let us know what happens. Have a nice thanksgiving :)

Thanks. I’ve already changed the module.
Have a thanksgiving

Yes, sorry about that, back to checking the power and ground inputs at the HVAC controller when the system is not working.
