So recently my A/C display no longer shows up. I looked around and most people had a problem with their whole center console display, but I don't

My radio works fine, air blows, but seems to be just outside air.

I checked all the A/C Fuses, the one in the cabin by the door, the 10 amp under the hood, and the square black one under the hood as well. They all seem fine.

The car is stock.

I can't find anyone who has had this specific problem, and figured it was time to come to the experts....

Help!

attached a pic of the display.

 

Did you ever figure out what this was? I think I have the same issue.

 

Try pulling the radio out and checking the connector that goes from the radio to the display.

The last time I had my radio out (tracking down a rattle), I forgot to reconnect the display cable and it scared the bejeezus out of me.

Unfortunately, it wasn't that.

The radio and heater controls were swapped into another RX8, and they worked perfectly, so not that either.

 

Well, did you check the wiring harness at the display end of the cable?

 

No, If that wasn't connected (or had issues) would it still cause things like defroster not to work?

 

Good question. Let us know if you find out.

 

Yeah, I'll post whatever it ends up being.

 

In the end, it ended up being a bad wire bundle at the connection to the AC amplifier.

 

My display also does not show any of the heater info, or the temperature. However, I also cannot change the temp my heater blows, my rear defrost doesn't work, and the heater only blows out the dash vents. I can't get it to switch to defrost or floor. Can you possibly tell me where to check the connections for the display?

 

Access the plug that is powering up the control panel. Unplug it and plug it back in. I don’t know why this happens. I’ve come to deal with it. It happens every month or so. I hope that helps.
