Blend Door Replacement Problems - Help
So when I bought the car a few months back I swapped out the orings in the EATC just because it seemed like an easy preventative. So I did that and all worked fine. Then a few days ago the blend door actuator went out and the temp wouldn't change, only stuck on cold. So I did the self diagnostic which showed code 51 (sunload sensor) and code 24 (blend door actuator). So I bought a new acutator today and have it installed. Checked everything and while it works (and the other one didn;t) to change temps, now its stuck in defrost and floor. I listened for any vacuum leaks and checked the hoses into the eatc, as well as where the join by the passenger floor, and then behind the eatc where they go into the canistors and all looks good. The only vacuum sound I can hear is in that hole beside the eatc unit, where the white hose connects up to. It does have vacuum through the hole, but the hose isn;t leaking anywhere...so is that normal.
Any ideas on this?
