most of the time when i'm driving my car the AC display doesn't come on which sucks cause i can't see what mode or anything its in but the radio display comes on and works fine and my ac i can turn it on and it works but any idea on whats wrong with it or how ti fix it?

 

The fan has to be on for the A/C to kick on

 

Read this DIY and be sure to do the temperature control **** diagnostic test.

 

will that fix the display ?

 

I would guess there's a good chance it would fix the display. First do the test and see what results you get.

 

but thats not my problem i can turn on the ac and the heat i just can't see it on the display screen it doesn't show the temp or mode or anything
