temp blend door location 97 buick pa

[360wayvin]

Its starting to get really cold outside and I have no heat from both sides. Changing the temp to 90 does absolutely nothing. I would like to know exactly where is the actuator that controls temp for both sides. And is there a manual way to switch it to heat until I get it fixed. Thank u

Actually, there are two blend doors, one for each side, that control the temperature for the front passengers. The driver side is underneath the hush panel (just unscrew it) near the ashtray. The passenger side is behind the glove box; open the glove box, then pull he tabs that are stopping it from falling out, and the actuator is right inside to the left.

A third possibility is the main actuator that selects between the heating and air conditioning. Unfortunately, its buried behind the radio/HVAC stack, and requires pulling almost the whole dash apart. Look at the above actuators first, because these are common failures in the climate control system. Are you getting A/C air, or is it just outside air that's not warmed up?

I figured it out. It was the driver side and passenger side actuaters
They were not switch ing properly. Thank you
