Default No A/C on passenger side.

I have an '08 CTS.

So the A/C on the passenger side stopped working.

I had someone check it with a scan tool and they said that the door is "sticking".

They quoted me a crazy sum to change the blend door actuator on the passenger side.

Is anyone familiar with the fuse reset procedure?

If that doesnt work, I guess I'll have to tear into the dashboard. Any DIY vids or threads on how to replace the passenger side blend door actuator?

Default 08 cts a/c

i have an 08 cts and thought i had the same problem. bought the new blend door but never installed it. a friend suggested that the freon might me low. so i added 1 can and the passenger side started working. that was a year ago and it's still working fine.

I had the same problem. Added freon and it worked. I think the system is designed to direct the last remaining cooling to the driver if the freon is low.
