AC blowing only hot air
Hello, I have big problem - AC blowing only very hot air. When I switch air on screen, blowing slightly cooler air, but itsn't normal cold air. I changed heater valves and climate control module. And nothing... Any ideas?

Damaged loom behind the front bumper, happened on mine. You need to remove the bumper , un wind the loom and repair the breaks.

Before you tear into the loom follow the other advice above.
You must see what the DCCV is getting as far as voltage before you can go farther.
You are just shooting in the dark and changing parts most likely won't fix it.
Do the troubleshooting first. Then purchase parts.
Did you put a new or used climate control module in?
New DCCV's have been bad out of the box too. Need to check all this.
Please don't tell me you put a used DCCV in?

That fuse supplies volts TO the centre wire of the DCCV. A faulty DCCV WILL blow that fuse. One of mine did that.
With NO volts in that wire the DCCV defaults to FULL OPEN, so HOT air all the time.
