Recently purchased and installed a Pioneer avic-d3, after finishing the install, the only thing that works on the HVAC is the blower speed. AC, defrost, blower direction, and heat/cool settings will not work. It is driving me crazy since it is summer and it is stuck blowing heat on the lowest setting at all times. Checked every possible fuse and they are all good, triple checked my wiring and there is no breaks or cuts, everything is plugged in correctly. I didn't even remove the hvac at all during the install so I do not understand how it became messed up, took it out out and it looks perfect. Anyone have any ideas?
