My car has the automatic climate control. When I want heat I have to set the temperature to 90 degrees. It blows out air at 110 degrees. If I change the setting below 90 degrees it blows out air at 60 degrees. I would like it to give 68 to 72 degrees. Does anyone have an idea as to what I should look for? It goes from one extreme to another with nothing in between. Thank you. I only have a few days to figure out the problem.

You have to do the self diagnostics on this see the picture for details and if you get a code get back to us. If code is 888 then that means nothing is wrong with system. I have included a possible problem for yours though. You have to have key on to do self diagnostics. It will have codes 1-5

I followed instructions. Within 20 seconds the "888" came up. It sounded like it was testing the doors.

It tests most of the controls so there is nothing wrong with that, check sensor that I also had there. Picture shows instructions on how to remove it but you will have to do the same thing to check it. It will look like what is in picture. If that does not take care of it then you will have to have a professional look at it as it may be something else.
