Yet another Hvac issue... Please help

I know that this issue has been discussed extensively on this forum and all across the internet. I am just trying to gain some more insight on my specific issue so please be patient with me. Please don't write me off and tell me to just Google the answer. I know there are threads everywhere about it however I'm just trying to gain a fresh perspective from someone because I've been reading about it for days.

I have a 2001 c5 Corvette with the following HVAC error codes: b0361, b0363 and b0441. From what I read these are pertaining to the driver's side blend door actuators. This lines up with my current problem which is the heat is stuck on and the temperature does not change even though the compressor is on and the system is fully charged. However my driver's side actuator is doing the same thing. It will not change temperatures and the blend door actuator does not move but it isn't stuck on full heat but partial. It appears that both actuators do not move. I have reset the codes reset the HVAC system pulled the fuses pull the negative terminal and unhooked the head unit. The actuators still don't move.

My question is this: does it sound like both actuators have coincidentally gone out in the same position? if the passenger side actuator is bad why am I not receiving codes about it?

Thanks for your time.

I've tried pulling fuse 27 in the footwell for at least 60 seconds, and it did work a few times. It no longer does the trick, and I'm getting tired (and sore!) of laying on my belly doing a "crapshoot". Ive decided that since the dash has to come out, I'm replacing BOTH actuators, and probably the evaporator, since I get hits on my A/C sniffer when holding it in front of the interior vents. Probably replace the 4 way flasher at the same time, because of occasional turn signal issues. From what I've seen on the Forum, the drivers side actuator can be replaced without dash removal, but it's not easy with the dash still installed. Even if you go that route, you'll have a brand new actuator on the drivers side, and a 20 year old actuator on the other side. I'd pull the dash and replace BOTH, and if there are 3 actuators, I'll be replacing all 3. I hear Dorman makes a good replacement. Good luck.......
