Default Blend door..?

So I'm sorting through my new to me 93. Fixed quite a few things but still some to go. I pulled and fixed my C68 HVAC control module and it seems to work properly but I don't get any heat until I run it all the way up to 90*. Is this the notorious blend door issue?

Try and maybe disconnect the battery for about a minute, it may reset.......Also were the plugs and contacts good?

I thought the blend door issue is the noise it makes when you switch modes. I could be wrong on that........My ZR-1 has always has had a loud blend door, like it's slapping on something.

I'm just guessing. The air diverts between floor/dash/defroster like it's supposed to. It doesn't seen to be modulationg air temperature properly.
