I am having an A/C issue, my air will not blow through dash vents. Air only comes out the defrost, and it is hot! This car has 2 Blend door actuators, but, would/could that be the problem?

Rare for both the Mode and Temp doors to go at the same time. Turn the system OFF, shut down and disconnect the battery for a few minutes. (Under the back seat, check for seat heater connector on passenger side). That MIGHT reset the door actuators.

Do a Google search - for hints in this forum or in Tech Tips. "cadillac forums 2002 seville hvac door actuators" or something close.

================================
MIX doors control the cabin temperature -

MODE door controls where the air blows from -

check for DTC - Diagnostic Trouble Codes -
post the code number - whether it is Current or History -
and don't forget to include the code DEFINITIONS -
