Help! 1994 corvette heater problems

[Ryan.m]

Hi everyone
I am a first time vett owner. And i have an issue that seems quite common. I have a 1994 with the electronic hvac control. All the functions seem to work well like they should. Except i have no control overtge the temperature. I understand that the mixing door could be problem. How can i test the motor? What voltage should be there? And how is it accsed?
Thanks any help would be greatly appreciated

Hi Ryan and welcome to the

I can't help with your tech inquiry but I just wanted to jump in and say a quick hello. My first Corvette was a '94 convertible so the 94 will always have a special place in my heart.

We've got some great tech minded members on our board so I'm certain one will be along soon with suggestions.
Good luck with your issue and enjoy the CAC!

Ryan, welcome

Just to make sure... have you measured the temp of the water sending / returning from the heater core?
Sometimes, the core is plugged or only partially flowing...

I would look there first....
