So the issues with this truck just don’t stop. Want to sell it so badly but put so much money into it already. The stopped working this am. I checked that the Freon was a bit low and I topped it up a bit with 1 can of r134a. Now the ac doesn’t work at all an cold air blowing. Before at least there was some cold air just the other vents were blowing hot air. Now as soon as I turn on the ac the aux fan starts running at full speed and it’s blowing hot air inside the cabin. Any thoughts on what I could do ?
