My bland door does nothing when i took it out i even plagged a new one in and nothing happened does any one have any input thank you very much

 

I just took them blend door acuator out because i thought it was bad because it was blowoing hot air on ac
so i unpluged it acuator and pluged in a new one and nothing happend can any one shed so light on this problem


ps u do not have to remove the dash to change the blend door acuator i got it out in like 15 min

 

Sorry.. I finally gave up after replacing my blend door actuator. It fixed my original problem of blowing hot/cold every 15 seconds. The gear inside was stripped out. My dash control to switch it from defrost to vent to floor still doesnt work. Along with the other problems I am having with this blazer I am seriously considering sticking a rag in the gas cap and setting it a blaze. This is by far the worst vehicle I have ever owned.
