Default C-68 issues solved I believe

my 90 would flash its indicator lights and while running a/c switch to warm air and the blen-door actuator motor could be heard running. basically the blendoor on hottest setting would open about 1/2 way and just flutter. However on a/c it would close all the way against the heater core.

I check the blendor motor and no gears were stripped and everything appeared normal. Then I took and installed a new blendoor motor and now on the hottest setting it will completely close to one side and when set to coldest setting it again goes to the other side fully closed. I also no longer hear this motor running like the other one did and my indicator lights no longer flash either.

so I am hoping this 60.00 motor has cured my problem. I will let you all know when I get everything back together how it does. But so far I can visually see the blendoor responding to any temp changes immediately.
